BLE disconnection: cif=3 connected=0 conn_id=3 reason=0x0013

Postby tharunjoy » Fri Sep 06, 2019 7:42 am

Hi,

I am trying to build an ESP32 as a BLE GATT client to receive a connection from BLE remote(ATB110x). While trying to connect to the device I am immediately disconnecting from the server.

Code: Select all

 
W (23898) BT_APPL: bta_gattc_conn_cback() - cif=4 connected=0 conn_id=4 reason=0x0013
I (23908) GATT_CLIENT :::: EVT 41, gattc if 3
I (23908) GATT_CLIENT :::: ESP_GATTC_DISCONNECT_EVT, reason = 0x13
0x13 defines : Remote User Terminated Connection

I have connected this remote to android devices and It was connecting without any issue. What am I missing in esp client side? How should I address it?

Hi,
I have to add one more analysis to this.

'ESP IDF is getting disconnected when the peripheral device stops advertising'.

How to stabilize the connection even after the advertisement stops?

Based on your earlier description I thought it may be problem with connection parameters update, which device may not accept and disconnecting.

After reading your last update I am starting to think you are trying to connect esp32 and android device at the same time to peripheral that can use/handle only 1 connection.

Hi @chegewara ,
'ESP IDF is getting disconnected when the peripheral device stops advertising'.
I found this based on one of my analyses on ble server(remote) disconnection from ble client(esp32).

Before I was worried about my server configuration, so in-order to replicate another ble server I downloaded an android app https://play.google.com/store/apps/deta ... eral&hl=en. Using this app I was able to simulate a battery(ble server) and connect to ble client(esp32). I was able to connect and read the value from this app until I stop advertising the app(App Screen off will stop advertising). After I am getting the same error that I used to get when I tried to connect to the remote, where the remote use stop advertising when get connected.
Based on your earlier description I thought it may be problem with connection parameters update, which device may not accept and disconnecting.
I am attaching the code here. Please let me know if I am doing something wrong.

The issue was with the server device as per the reason=0x0013:: ESP_GATT_CONN_TERMINATE_PEER_USER
Reconfigured the BLE_GATT_Server device and the issue was resolved.

Hi Tharun,

I am facing the same issue, could you please elaborate how you reconfigured the server. Thanks in advance.

Hi tharunjoy, I experience the same kind of problem as you describe above: disconnection of an ESP32 client from a ATB110x BLE remote after a couple of seconds.
How did you get the issue fixed?
Thank you!
