Hi, Could you please help me with below query? Usecase: Have 2 temperature devices connected and set the CCC(Client Char Config) to receive the temperature updates. Issue: -- In attio_connected_cb we are calling g_attrib_register(user_data) were we are passing the "user_data" which has the "Device Reference". So in the callback function "notif_handler" we are getting notified from the 1st connected device, using the "user_data" we are trying to get the "Device Reference", which has the data/info of the 2nd device rather than the 1st device. How do we retrieve the handle/device reference for the device which is sending the "NOTIFY"? Thanks, Vijay Member of the CSR plc group of companies.
