Why I can`t post question in any group?
This question i want to post in STM32WB55 but receive error "You can't add new topics, so select existing topics for your post"
Hi.
I use characteristic with properties: CHAR_PROP_WRITE | CHAR_PROP_NOTIFY.
And after enable notification on this characteristic, when to write any data to them, notification fire 2 times.
Example:
1. Enable notification from peer.
2. From peer write data to characteristic.
3. When EVT_BLUE_GATT_WRITE_PERMIT_REQ event raised, async or sync change characteristic value by aci_gatt_update_char_value.
Result: in peer, notification will come 2 times. If change characteristic value by aci_gatt_update_char_value after delay, first notify came at once after write, second notify came after delay.
How can this be explained?
