How to receive nRF51 BLE device from android phone notifications?

[enes.sakut]

Hi I'm creating an android app for smartwatch(used nrf51 ble),I have two questions

1.I used ANCS(Apple notification center service) in my android app,but nrf51 device didn't read anything.I added ANCS UUID,characteristics and descriptors,but nrf51 didn't fire onCharacteristicReadRequest metho.How can I solve this problem?

2.If I can't use ANCS for android app,what can I use to receive all android phone notiifcations?

Thanks:)

Device doesn't suppport to UART.I'm sure it has to do a write request,but I don't know other way?How can I enabled notificaion on the ANCS server on the android phone?

I don't really understand you. Which write request are you expecting ? You need to write to the CCCD characteristic to enable notification.

Which ANCS firmware are you testing ? Please try to test your device with nRFConnect on PC as described in the documentation before you proceed further.

Ok sorry about wrong information I deleted all byte arrays and device send to write request but now I think we have to see Read Request.Am I right?

I really don't understand.

Could you please describe how do you expect ANCS works, in general?

And how it doesn't work as you expected on your implementation ?
