RE: Can't receive multiple notify characteristics on android, send by nrf52840

Hi,

Activating and receiving notifications from multiple characteristics (and multiple services) should not be a problem, as that is what BLE is made for.

Can you check with nRF Connect for mobile, or nRF Toolbox, to see if enabling notifications there gives you notifications from all three services? That will show you if the issue is in the nRF device or in the Android app.

I also need some more information regarding your nRF application and Android app. (I.e. for the nRF side: Hardware, SDK version, Softdevice version, libraries used, what example it is based on if any. For the Android side: Hardware, Android version, libraries and APIs used with versions, what example it is based on if any, etc.)

Also, a sniffer log may prove valuable in figuring out what is happening and where it fails.

Regards,
Terje
