Another problem I just observed is I am losing some factory settings (i.e. car logo) and also all radio stations when doing a HU reset (by clicking on/off button for some seconds).

Before upgrading to HA this was not happening.

Do you know how to fix this issue?.

Thanks

Hi. Sorry because I didn't see your message sooner. Yes, I soldered the rf210 in j11 slot and you need to solder wires like I described if you want to work.


I don't know about BW124 and about MCU HA, yes it's working very good and I have Android 10 form Hal9k.

Where can you get this Android 10 version? I am not able to find it in the Yandex link

MCU is not android. Modded roms by Mal and hal are problems- save your money.

Search yandisk for .IMG files such as HA. Use OTG to flash.img and then update to latest OTG

Thanks marchnz, I have already found the .img files at Yandisk, but I do not know how to upgrade my unit from Android 8 to Android 10. I am not sure how it works, could you please help me?. Thanks

Hello all,
I have a problem, I changed to RF210 in settings and now I cannot get wifi access. I am using a 4G wifi modem and need to get internet access.
Do you know if it possible to connect to internet via Wifi and use Rf210 for Bluetooth?
Thanks

But I do not see any marks with RX, TX, +5V or GND.

Or should I weld directly there the module? In this case in what position?

Thanks

    I confirm that RF210 doesn't work with 11pin motherboard #67. It is recognized on android 9 and 10, but for both versions the phone calls didn't work as I couldn't hear anything neither the call receiver. I would like to thank @abdelmonem who solve this issue by changing the Bluetooth module.

    Yes, the header is correct, unless the header is for DTV like my unit.

    I have no clue how this would look like.

    what I would do is wire according to the schematic. Probably easier said than done, but doable.

    Well, I guess there is no schematic included in the ali offering. Neither for my unit. So I will likely have to follow some traces. Or just solder it and watch out for some magic smoke.

    However I believe the pinout is likely always the same on those units. Same as for those USB daughterboard modules (see my other link). However here at least the boards are usually labelling the pins.

    I actually ordered one of these modules and will have a look. Perhaps soldering it into my bench unit first (replacing the WQ_BC5 module). If no magic smoke escapes I can search for the correct module type in factory settings and then solder it to my car unit.

    Well, to be honest I am quite OK currently with HAL Android 9 on my car unit so I will see when I got time to try this.
