Characteristic read event/callback

[adnan arshad]

Hi,

I am using ble_app_uart example and want to detect the read evant/ call back. Kindly help me how to register a call back function of a read type characteristic. I want to update the characteristic value on reading dynamically.

Hi,

This can be done by using the GATTS Read Request with Authorization. See this sequence chart on how to implement this feature.

Best regards
