Error: "BT: bta_gattc_cmpl_cback unknown conn_id = 1, ignore data"

Postby newsettler_AI » Tue May 22, 2018 10:35 am

Hi,

I'm trying to establish connection bewtween 2 ble modules: esp32 as gatt client, nrf52840 as gatt server.
On Nrf52 3 services are running: Battery service, Device name, Heart Rate (basically, its default example from manufacturer).

On esp32 side I have sucessfully discovered and connected to nfr52 as gatt client, and read data from battery service ONCE.
After that I got next error:

BT: bta_gattc_cmpl_cback unknown conn_id = 1, ignore data

And 30 seconds later I got disconnect (connection dropped by timeout):

BT: bta_gattc_conn_cback() - cif=1 connected=0 conn_id=1 reason=0x0013
BT: bta_gattc_conn_cback() - cif=2 connected=0 conn_id=2 reason=0x0013
BLE: (battery)ESP_GATTC_DISCONNECT_EVT, reason = 19


I dont know what is the problem with unknown connection?
