I have a ESP32 WROOM-02 board, which works fine most of time. set to work as WIFI-AP mode, the device can connect and send/receive data without any issue.
However it will randomly reboot if let it run for awhile, sometime it takes 30 minutes to reboot, sometimes it takes several hours to reboot.
From the serial port, it shows following 2 lines message right before reboot:
tx rts error 0x16
mac 1370
I have tried to replace the nonossdk with various versions (below 3.0), there is no difference.
ESP8266 sdk v2.74 was used, and all other versions below 2.74 had been tested too, got same error.
Upgrading to high version (>3.0) is causing other issue (device cannot get IP once connected), there is no other option, besides I have to use 'lwip v1.4 compile from the source' option other than 'lwip v2.0', so v2.74 is the best one I can use.
Anyone has seen this issue too? It runs fine most of time, but just not stable and it cannot be released to the customers b/c of this rebooting issue.
I really cannot find where the 'tx rts error 0x16' coming from, neither know what this error really means.
Thanks advance for the help.
John
