Gamepad using nRF52832 chip works for some android games, but not for some others, and only partially work for some other other.

Hello,

We have developed a new type of smartphone gamepad using the nRF52832 chip.  But for some reason, it works for some games and not for others.  And only partially work for some others games.  We compared the games with cheap generic gamepads off of ebay and the cheap generic gamepad works for all these games.  We really can't figure out why this is.

We are willing to contract someone to look over our source code to see why is this happening.

Thank you

Duncan

I will look into that.  Are there any sniffer trace methods or apps that you would recommend?

Thank you

Hi Duncan

For best performance nothing beats a proper Bluetooth sniffer like the one from Ellisys, but these are very expensive. 

A much cheaper option is to use the Nordic sniffer solution, documented here, which allows you to sniff Bluetooth packets using a normal nRF devkit or dongle and a PC.  

For picking up the service discovery and HID report exchange the Nordic sniffer should be more than sufficient. 

Best regards
