What happened?

When trying to reconnect after startup using an 8BitDo SF30Pro, the connection does not reliably establish. This also happens with other Controllers.
This is happening on 3.10.3, Arduino, 2 GamePads enabled in config.

On 8BitDo I‘m trying to reconnect by pressing the start button.

How are you reconnecting it ?
Are you just doing the re-pair again ? or what button are you pressing ?

And what does it mean "not reliable establish" ?

And when you have the chance, attach the logs

hello ricardo. i have the same problem as bbsan2k on my gbahd. the problem is not the 8bitdo but also other controllers. if i pair a controller with the esp then it takes up to 2 seconds. after that i can use the controller normally and it runs stable. but if i then restart the controller and try to connect then it either takes a very long time or is not found at all. so i currently have to pair the controller again most of the time.

hello ricardo. sorry for the delay. we had to activate the log in the firmware first.

Tested: 8Bitdo SNES30 GamePad

pairing allways works stable (8bitdo: holding select):

I didn't know that 8BitDo controllers support "reconnect" by just pressing Start.

I don't have the SNES30 Gamepad, but I'll try to reproduce it with my other 8Bitdo controllers

Hi, I have the same issue with the Xbox Wireless controller (3 button). Pairing works 100% of the time. However, when I press the Xbox button to turn the controller on, it automatically reconnects, If I hold in the Xbox button to turn off the controller, it disconnects fine and reconnects when turned on again. The problem is now that the controller turns itself off when not in use after a while to save battery and in this case the controller disconnects, but then I get:

When the controller disconnects due to battery saver:
uni_hid_device_disconnect: Unknown GAP connection type: 0

On trying to reconnect by turning the controller on:
uni_bt_le_on_connection_complete: Device not found for addr: XX:XX:XX:XX:XX:XX

I am using it in Arduino IDE with a custom made ESP32 board, but similar to a Wemos D1 mini setup.

from @john3dc logs, I see Removing key for device: E4:17:D8:33:0D:79. which means that the ESP32 is removing the bonding key... meaning that re-connect will fail.

I had to add that hack to improve connections on some devices. I can try removing it and see what happens.

In any case, make sure that your sketch DOES NOT have this line:
https://github.com/ricardoquesada/esp-idf-arduino-bluepad32-template/blob/1c4cb01c261961fe6dce3d323b09ed774f9511c8/examples/ota/main/sketch.cpp#L103

this will prevent re-connections after a reboot
