Rock 3B Android + 4G Module

ROCK 3 Series 3B
1

Hi,

I’ve got the Rock 3B SBC and a 4G module from waveshare (link below).
https://www.waveshare.com/product/sim7600x-h-m2.htm
I installed the android image from radxa’s website but I can’t get the 4G to work.
I tried installing the debian OS and then installing drivers following these instructions, https://www.waveshare.com/wiki/SIM7600G-H-M.2#Set_up_4G_in_Raspberry_Pi. That worked fine!

But I don’t know how to install the drivers for the 4G module in Android.
Tried to connect to the sbc with ADB but it can’t find it.

Has anybody got the Rock 3B with android to work with a 4G module or know how to do it?

Our Android inage does not support this 4G module.

Oh, that’s a shame.

Hello,

So I got a reply from support that the Quectel EM05 is supported.
Installed the image dated 20240619 and 4G now works. But now I have an issue with the touch display that I’m using that I did not have with the image they have dated 20220408.

The touch is now off on the y axis (up and down). If I touch the display in the middle it’s ok but when i scroll up or down it trails a head. so the input moves further from the center than my finger.

How do I solve this?

Solved by adding a file to /idc named Vendor_xxxx_Product_xxxx.idc (xxxx replaced by the vendor and product number of the display)
