nRF5340 BLE write response

[Rantanplan]

Hello,

I'm using NCS 2.0.1 on a nRF5340 board.

Currently I have some troubles with getting a response if I try to write a BLE characteristic from an iOS app. The write property for this characteristic BT_GATT_CHRC_WRITE is set (and BT_GATT_CHRC_WRITE_WITHOUT_RESPONSE is not set).

Anyway, I'm not receiving a response in the iOS app. 

Is there a way to debug the network core or enable some debug messages from it, which might be useful to find out why the response is not sent?

Many thanks for your answers in advance.

Hello,

I found my mistake. I was accidentally calling bt_gatt_notify in the read callback which seems to block the response.
