What is Bluetooth?

Bluetooth is a wireless technology standard used for exchanging data between fixed and mobile devices over short distances using short-wavelength UHF radio waves in the industrial, scientific and medical radio bands, from 2.402 GHz to 2.480 GHz, and building personal area networks (PANs).

Bluetooth 5.0 is the latest version of the Bluetooth wireless communication standard. It’s commonly used for wireless headphones and other audio hardware, as well as wireless keyboards, mice, and game controllers.

The comparisons

Bluetooth 4.0 and 5.0 do almost all the same things, but they have their own features and differences.

Speed

Bluetooth 5.0 is faster than Bluetooth 4.0. The speed of Bluetooth 5.0 is 2Mbps, twice the speed of the Bluetooth 4.0 of about 1Mbps.

Range

Bluetooth 4.0 supports 50m in outdoor range and 10m in the indoor range, while Bluetooth 5.0 supports 200m in Line Of Sight path in the outdoor environment and 40m in the indoor environment.

Power requirement

With the low energy designed, Bluetooth 5.0 uses less power on your device compared to the Bluetooth 4.0.

Message capacity

The Bluetooth 4.0 has a small message capacity of about 31bytes, which gives just 17 to 20 bytes for actual data payload. While the Bluetooth 5.0 with a large capacity of 255bytes gives more bytes for actual data payload.

Bluetooth beacon

With Bluetooth 5.0, beacons have become more popular due to the speed and range increase while with Bluetooth 4, they are less popular due to the less speed and range as well as low message capacity of 31bytes.

Support for IoT devices

Bluetooth 5 easily meets the requirements for IoT devices with its good range and increase in speed while Bluetooth 4 does not due to its low speed and short working range. That means IoT devices will work well with Bluetooth 5 and utilize all its features properly.

Compatibility

Bluetooth 4 works best with devices that are compatible with version 4 series but will not work with devices that have Bluetooth 5 while Bluetooth 5 is backward compatible with v1, v2, v3, v4, v4.1 and version 4.2 but will not utilize all the features of Bluetooth 5.

All in all, the car radios with Bluetooth 5.0 can meet the more requirements and work better. Besides, Pumpkin 12.8” Tesla Style Universal Car Stereo posses the Bluetooth 5.0 feature.

Customer review on Pumpkin AA0495B 2 Din 7-Inch Octa-Core Universal Android head unit

I have a new Pumpkin car stereo and I am impressed so far. The device is Pumpkin AA0495B 2 Din 7-Inch Octa-Core Universal Android Infotainment System with GPS, RBDS Radio, and Bluetooth(4G RAM+32G ROM).

I have had this installed in my 20-year-old Focus for a couple of months now. It’s double din but it seems Fords version of double din is slightly different. I had to ‘modify’ the dash bezel to get it to fit, that is nothing against this device.

0495 ford 150

For the most part, it’s been excellent, I’m far from an expert in installing something like this but have it running with all bells and whistles (Bluetooth, wifi, backup camera, etc.). Having it display battery voltage on the main screen has been incredibly valuable to learn and understand the power consumption.

I don’t believe you can use this without the engine running for too many minutes before it bleeds too much juice from the battery, having a visual display of the voltage is so useful, it could just be my car and/or battery but it should be no surprise it’s more power-hungry than what was originally intended for my car. I have yet to look into possibly a larger battery to counter/accommodate it.

The other day the screen couldn’t seem to make it minds up on brightness level and flicked levels every 10 or so seconds, that hasn’t happened since, but it happened.

I am suspecting my starter motor may be on it’s way out as the ‘instant on’ feature is proving somewhat unreliable whereas initially, it worked great. Again, I have a 20-year-old car and new to this type of install, to me, there may be calculable reasons for the above and I do not believe it’s this device but rather my lack of knowledge and understanding. I say this as a caution to others, maybe get a professional to install and advise!

Other than that I’m really happy with it and it’s a fraction the cost of a bigger name brand with all or more features and it’s Android so massive potential in customization.

As for the design, having an actual volume dial was a key factor in me choosing this, the physical Home and Back buttons have also proven superior to the touchscreen options. One tiny gripe is the black outer bezel sticks out from the screen a touch too much, so when using the touchscreen on the top edge is a tiny bit awkward, but it’s not that big a deal.

Overall I very much recommend this device.

Customer Review on Pumpkin AA0412B 10.1″ Octa-Core Android 9.0 Infotainment System

It's only fair to share...Share on FacebookShare on LinkedInPin on PinterestShare on RedditShare on TumblrShare on StumbleUponDigg thisShare on VK

I have a new Pumpkin car stereo and I am impressed so far.

The unit is one of the first Android car units, which matches the European 2-DIN size without the need to rework anything.
The screen is bright and easy to get it into the right position, the screen mount is really stable and no flutter on bad roads.

The first impression of my new Pumpkin 10.2″ unit AA04121B-D01

Since the weekend I have the new pumpkin here and have it extensively tested on the power supply before I installed it in the car yesterday.

Scope of delivery:

  • 2 DIN Unit
  • 10.1 inch glossy screen, with metal frame
  • Cable set with 2 USB ports
  • User manual English/German

Hardware:

  • PX5
  • 64-bit 8-Core Cortex-A53 1.5GHz
  • Android 9, build number 201907251651
  • MCU: CSN2_06252ß19_163051 (Despite this MCU the device is obviously a KLYDE device)

First impression
I must say, the first impression is very good.
The first start was done after about 20 seconds.
The original launcher is as usual from Pumpkin, as well as the apps included.

What’s new:

  1. Additional USB on the front panel
  2. 2 micro SD trays on the front panel
  3. Volume control knob (illuminated)
  4. Knob for App switching (illuminated)
  5. App called “Tachograph,” a new app for the Dashcam.
  6. Caravan, an app that supports rear view camera and front camera and you can switch between both cams.
  7. Sync (I don’t know what it’s for yet)
  8. CD player for external CD players
  9. An app called “Joykey Study” for certain OEM-Key-Pads, I have to do some research myself…
  10. VoiceControl App Looks like an app for Apple friends. The app doesn’t work for Android phones (at least not for mine).
  11. The Settings menu was cleaned up, also the menu for the “factory settings”. Here you don’t find the strange menu anymore, but it’s neatly arranged. Unfortunately not in German, but I think you can live with that. The PIN for the factory settings is still 126.
  12. Display of the battery voltage in the status bar is now possible in the “Personal settings”.
  13. Also, the settings of the phone can be displayed now. Here you can see the field strength and the battery status at the top of the status bar.

The radio runs very smooth and I was able to install all my needed apps without any problems. Root was possible with the known method without any problems.

The screen is connected to the radio with a flat cable plug, just slide it in and click to fix.
You can turn the screen with a little effort in all directions, but the mounting makes a very stable impression. There is also no clattering.

First Tests:
The working temperature is important to me. With active route guidance, DAB+ active in the background, Blitzer.de active, the temperature stays below 60°C… and that without any additional actions such as heat sink installation and fan.

The last 2 weeks on the road in the day and night mode have been as expected. No real bugs were visible.
One thing that needs to be said: If you switch the screen in night mode to the darkest possible brightness, you will find out that the backlight is a bit flickering. This is no big deal, just move the slider one step up. The brightness is the same but without flickering.
Experienced users are able to root the device and afterward to enable the developer menu.

Pumpkin AA0412B Android 9.0 universal head unit

Seit dem Wochenende habe ich das neue Pumpkin hier und habe es erst einmal ausgiebig am Netzteil getestet, bevor ich das gestern im Auto eingebaut habe. Einen Bericht über meine Testfahrt folgt…

Link zum Radio: Pumpkin Android 9.0 10.1 Zoll Universal Autoradio Radio IC TEF6686 Octa Core 4+32G Doppelt Din mit GPS Navi

Daten:

  • Lieferumfang:
    • 2-DIN-Unit
    • 10,1 Zoll Bildschirm glänzend, mit Metall-Rahmen
    • Kabelsatz mit 2 USB-Anschlüssen
    • Bedienungsanleitung Englisch/Deutsch
  • PX5
  • 64-Bit 8-Core Cortex-A53 1,5GHz
  • Android 9, Build-Nummer 201907251651
  • MCU: CSN2_06252ß19_163051 (Trotz dieser MCU ist das Gerät offensichtlich ein KLYDE Gerät)

Hier noch einmal der Hinweis auf die MCU:
Es handelt sich um ein PX5, allerdings mit einem neueren Mainboard. Die CSN2-Geräte sind nicht firmware-kompatibel zu den gekannten PX5-Boards, somit entfallen derzeit Custom-Roms.

Erster Eindruck:
Ich muss sagen, der erste Eindruck ist sehr gut.
Der erste Aufstart war nach ca. 20 Sekunden erledigt.
Der Original-Launcher ist wie gewohnt von Pumpkin, ebenso die mitgelieferten Apps.

Was ist neu:

  1. Zusätzlicher USB an der Frontblende
  2. 2 Mikro-SD-Einschübe an der Front
  3. Drehregler für die Lautstärke (beleuchtet)
  4. Drehregler für App-Umschaltung (beleuchtet)
  5. App namens “Fahrtenschreiber”, eine neue App für die Dashcam.
  6. Caravan, eine App, die Rückfahr-Kamera und Frontkamera unterstützt und man zwischen beiden Cams umschalten kann.
  7. Sync (da weiß ich noch nicht, wofür die da ist)
  8. CD-Player für externe CD-Player
  9. Eine App namens “Joykey Study” für bestimmte OEM-Key-Pads, da muss ich selber noch forschen…
  10. VoiceControl App Sieht mir nach einer App für die Freunde des Apple aus. Für Android-Phones (jedenfalls für meins) funktioniert die App nicht.
  11. Das Settings-Menü wurde aufgeräumt, ebenfalls das Menü für die “Werkseinstellungen”. Hier gibt es nicht mehr das seltsame Menü, sondern sauber gegliedert. Leider nicht auf Deutsch, aber ich denke damit kann man leben.
  12. Anzeige der Batteriespannung in der Statusbar ist jetzt in den “Persönlichen Einstellungen” möglich.
  13. Außerdem werden jetzt auch auf Wunsch die Einstellungen vom Telefon angezeigt. Hier sieht man dann die Feldstärke und den Akkuzustand oben in der Statusbar.

Das Radio läuft schon mal sehr flüssig und ich habe alle meine benötigten Apps problemlos installieren können, Root war mit der bekannten Methode über ADB problemlos machbar.

sdr

Der Bildschirm wird mittels Flachkabel-Stecker am Radio angeschlossen, einfach nur drauf geschoben und rastet ein.
Man kann den Bildschirm mit ein wenig Kraftaufwand in allen Richtungen drehen, dabei macht die Halterung einen sehr stabilen Eindruck. Da rappelt auch nichts.

Erste Tests:

  • Wichtig für mich ist die Arbeitstemperatur. Mit aktiver Routenführung, DAB+ im Hintergrund aktiv, Blitzer.de aktiv, bleibt die Temp unter 60°C… und das ohne irgendwelche Maßnahmen, wie Kühlermontage und Ventilator.
  • Gestern habe ich das Radio dann mal eingebaut. Als Erstes fiel mir auf, dass Pumpkin sich bei diesem Radio endlich mal an die in EUR üblichen Einbaumaße hält. Meine bisherigen Radios benötigten immer Nacharbeit am Einbaurahmen. Ein neuer Rahmen ist somit fällig, weil der vorhandene Rahmen zu groß nachgearbeitet wurde.

Verbesserungspotential:

  • Entwicklermenü ist Passwort geschützt. Das PW hat wohl nicht einmal Pumpkin. Es sei geheim….Aber ich bin dran. ;)
  • Das neue Android 9 Design von Pumpkin ist derzeit noch in der Mache. Bin mal gespannt, wann das kommt. Da zeige ich demnächst mal ein paar Bilder zu. Das sieht sehr schick aus.
  • An meinem Auto funktionieren die Telefon-Tasten gerade nicht, sie werden von der App nicht erkannt. Ich musste also meine Spracheingabe-Taste umfunktionieren, dass ich über das Lenkrad einen Anruf annehmen und auflegen kann (Doppelbelegung der Tasten geht über long click)

Kaufempfehlung

  • Für alle User, die gerne einen großen Screen haben wollen, mit einer stabilen Firmware –> ein uneingeschränktes JA
  • Für alle User, die lieber ihr Gerät über einen guten Launcher statt überladener Custom-Roms personalisieren wollen –> uneingeschränktes JA
