ESP32/nimble forgets BLE pairing connection to Android client

[eduardocintas]

I think we are affected by this ESP/nimble issue, it have a fix but is on a branch still not merged. So i don't know hot to set ESP-IDF to use that branch.

Any advice appreciated, i will try patching manually to confirm if resolves out pairing Issues.

Nice looking. Although I'm not sure if we're using ESP/Nimble indirectly as we're using h2zero/esp-nimble-cpp. I'll keep an eye on that issue and I'll bump the module once it's completely fixed if needed, as it's an nasty fix right now.

Tried "nasty fix"(manual patch) and solved Android pairing(So we are using it).

Windows still have same Behavior. I think we are affected by this Issue This post describes our proble exactly, i think ist whats happens.

Sadly issue have no updates from February, i will check a related one, i think they moved the discusion there.

I have tried esp32-ble-gamepad example, and got same windows connection Behavior, so we can discard a problem on our code. pretty sure is a esp-nombre issue.

Updated all components to latest versiones and got Android pairing Ok without need for Nasty fix. Windows pairing still working only at first connection. Searched on issue trackers to no avail and got no solution. Finally changed a lot of thing on menoconfig (what makes me sense that can be related to problem) now it's working OK on windows. On weekend will start over and go 1 by 1 to isolate the config involved.

Talked too fast, i can now turn bt off and on get reconnected and works OK, can even reboot windows and still get reconnected and works ok. but if i powercicle esp32 i get paired-connected loop same as b4. #$@!!

Could you upload the code to a zip or to a repository so I could check what could be wrong?

With Nasty Fix

Finally i have BñuN64-ESP32 based on Main

With following changes: N64-blueretro/main/main.cpp, with BLE-Gamepad sample to easier test and discard aur code as possible culprit

sdkconfig.defaults changed to lit the led on my board:

n64-sdk\n64-components\include\n64-pad.h with defines to adjust based on board tyoes

n64-sdk\n64-components\Kconfig with changes to be able to select new pinouts on menuconfig:

n64-blueretro\sdkconfig and n64-switch\sdkconfig have Many changed not done by me. I think they are auto detected at build

I will make a new branch with my code if u like to test.

Cant create a branch, so forked to do so: https://github.com/eduardocintas/BluN64-ESP32/tree/Eduardo-Cintas

You can get my code base from there if u want to test. Sould be good to make a discord Channel or telegram for better comunicación . With Victorkte and Yakara i think we are 4 active on the project,
