with ESP32 connecting to 6 BLE devices about nuttx

[acassis]

@tmedicci Did you know what could be this issue?

@WJ-JAY does this issue happen if you connect only 1 BLE device? Or only 2 devices?

[WJ-JAY]

@acassis I can try later, but connecting 6 BLEs is our top priority. We are eager to solve this issue, and we would greatly appreciate it if we succeed. In the future, we would like to enable both WIFI and connecting to 6 BLE devices simultaneously. Is this also possible?

Hi @WJ-JAY ,

Please try enabling stack coloration to check if it isn't a stack overflow (CONFIG_STACK_COLORATION). If you identify some task whose stack is near its capacity, please increase it.

Also, there is a list of saved interrupt states that contains NR_IRQSTATE_FLAGS entries. It is initialized here. Try to increase CONFIG_ESP32_BLE_INTERRUPT_SAVE_STATUS to let more interrupt states to be saved.

Hi @tmedicci ,
I made adjustments to the stack sizes of each thread as you advised, but the previous issue still occurred. It seems that the problem is not caused by stack overflow. I also set CONFIG_ESP32_BLE_INTERRUPT_SAVE_STATUS to 5. Below is the log when the issue occurred. Please help analyze, thank you.
