Hi,
We're using nrf Connect SDK v2.4 and have issues when calling bt_gatt_notify() from our main thread. The bt_gatt_notify() function blocks even though we have the CONFIG_BT_L2CAP_TX_BUF_COUNT parameter set to 20. What is the earliest version of the SDK which will not block when calling bt_gatt_notify() if one exists? Is there a function we can call to determine how many notifications are pending in the transmit queue?
