nRF8002 notifying host on change in input pin

[karthik k]

Hello I am using the nRF8002 kit. I would like to inform the host (Android app) when there is a long button press on the input pin.

Is this possible and if so which BLE profile / service should I be using for this ? I tried to use the "Immediate Alert" service but that service can only send data from the phone to the nRF device.

Thank You

Hi Balaji

Thank you for the response.

I have configured the nRF to use the immediate alert (master) as you have suggested. But the challenge I face is this.....

The immediate alert profile has only a "write" characteristic i.e it does not have a "notify" characteristic. With a "write" characteristic, the client (Android phone) can only send data to the server (nRF device).

My question is how to send the pin change information back to the phone ? Please let me know if I missed something.

What needs to be done on the Android side to get the pin value change information

Thank You
