How can NRF53832 receive a response from peer as central?

[chenwenjing5]

Hi, all,

I try to use NRF52832 as central and peripheral. When it is connected with peer as central, I try to send to peer a message with "sd_ble_gattc_write", but I can not find a way to receive the response(such as a notification) from peer, can anyone please offer me a way to do that?

Will the Nordic UART Service (NUS) be help? But by my understanding, the NUS needs peer working with uart, but my peripheral here has no uart service working on it, so I don't think it is a good idea, am I right or wrong?

Hi

What kind of response is it that you want from the peripheral. If possible, I suggest you implement the battery service in the peripheral and central and try to retreive the battery level from the peripheral device (see the ble_app_hrs_c and ble_app_hrs for example). The bas_c_evt_handler function should be helpful.  If the only goal is to see that you are able to receive anything from the connected peripheral, this should be pretty straight-forward. 

Best regards,

Simon
