Crash after attempting to connect and bond for more than 3 devices

[ovi1337]

I have currently a project with 5 ESP32 H2 devices, one is the Master and 4 Slaves, all 4 clients should be bonded automatically but it's working just for 3 devices and when it's connecting the 4th device is the Master crashing with the log below.
It's also every time another device which is not connected, so it's not depending to a special device.
The data transfer is also very small and with a delay of 5 seconds, so the stack should'nt be overloaded. These parts are working very well and i'm also not using the delay function at all, so it's not thread blocker in the code.

I hope that someone can help me to solve this issue somehow, because i have no idea why it happens and how i can solve it.

I'm currently trying to solve the issue with these parameters, but it's simply not working:

CONFIG_BT_NIMBLE_MAX_CONNECTIONS=9
CONFIG_BT_NIMBLE_HOST_TASK_STACK_SIZE=8192
CONFIG_BT_NIMBLE_MAX_BONDS=9

The rest of parameters are default.

I'm using:

h2zero/NimBLE-Arduino @ ^2.3.6
Arduino Release v3.3.2 based on ESP-IDF v5.5.1.250929  (pioarduino stable, latest release)

Here is the full log of the connection attempt:

[h2zero]

I'll see what I can do abut this, not sure if it's fixable though. This is caused by the config in the arduino core I believe, since these chips have their own porting layer we may be stuck with a 3 connection limit and would need to move to esp-idf to change it.

[ovi1337]

Thank you for your quick reply.

Can I change it maybe by hand in the framework itself and could it work then?
But the hardware itself should work right?

[ovi1337]

Well... I've tried it to change the Parameters in the Arduino Framework but it doesn't work. The compiling warnings are gone but the issue is still there 😢

I hope you will find a way somehow because I don't like to reactor the whole project to IDF 🤔

[h2zero]

What did you do to change the framework, custom libs from the lib builder should work.

[ovi1337]

I've tried to adjust the parameters in .platformio/packages/framework-arduinoespressif32-libs/esp32h2/dio_qspi/include/sdkconfig.h

I'm using this version, because the official Arduino Framework still doesn't support the H2 somehow:
https://github.com/pioarduino/platform-espressif32

I've changed these parameters:

#define CONFIG_BT_NIMBLE_MAX_CONNECTIONS 9
#define CONFIG_BT_NIMBLE_MAX_BONDS 9
#define CONFIG_BT_NIMBLE_HOST_TASK_STACK_SIZE 8192

[h2zero]

I think adding CONFIG_BT_LE_MAX_CONNECTIONS=9 as well will fix it, this causes the controller to increase the buffer count.

[ovi1337]

I've currently tried it, but sadly not:

Hmm I will have to try this with esp-idf, could be an upstream bug. Sadly all the controller stuff is a black box so we are at espressif's mercy on this. I can see the code that causes this but I cannot change it as it is precompiled with the Arduino core and the function that is called within it is some binary blob function :(

I've also tried the #develop build of the pioarduino framework, but it's the same issue but the error is a bit different :(

Same error actually, not enough callout buffers :(

I've tried to adjust the parameters in .platformio/packages/framework-arduinoespressif32-libs/esp32h2/dio_qspi/include/sdkconfig.h

This is an INFO in Arduino core which settings have been used to compile the Arduino libs. Changes here do NOT change anything in the libs. You have to compile the Arduino libs with settings which fits to your needs!

Only way is using Arduino as a component of IDF or HybridCompile. Both ways are supported in pioarduino

Thank you for your reply @Jason2866.

The warnings itself are completely gone.

I've already using the Arduino Framework as an IDF component now and have also tried to configure these parameters by menuconfig, but the issue is exactly the same as before. That's why I've opened the issue in the framework as well.

Upload the whole project on github. Your pio setup is most probably not correct.

(... Oops, whrong account 😂)

Sure, I will try to shrink the project down to just the connection part and will upload it today.
