Notify/Indicate limitation of count?
Posted: Mon Aug 10, 2020 6:49 am
Hi all,
I have 4 BLE peripherals connected to a ESP32, each with 3 characteristics that have notification.
Calling the function ‘esp_ble_gattc_register_for_notify’ the response for each of the 12 calls is ‘ESP_OK’, but from the 8th call on, I always get the debug message “BT_APPL: Max Notification Reached, registration failed” and the notification does not work afterwards.
Why does this function return OK if it is NOT OK?
Is there a limit for the count of registrations for notify or indicate (probably of 7) ? If so, how can I change it ?
Thanks a lot for your help!
Kind regards
Rolf
