Re: ESP_OTA: OTA image has invalid magic byte

Thank you guys..
I found the reason for this issue. Just like you guys told ESP is not able to automatically redirect the URL like a web browser. I just found the redirected URL and used that in the program, to successfully do an OTA update.

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

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.

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

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 downl...

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

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?
