I have flashed AT formware 0.50 binaries in my ESP-WROOM-02 module and it successfully started with AT version is 0.50 and SDK version is 1.4.0.
I have executed some AT commands on my module which works fine without any issue.
But, I have observed that my WIfi Module is restarted randomly when it is in idle state in AP or STA or both AT+STA mode. I have applied 3.3V Power Supply to Wifi Module externally. So, No any doubt for Power Triggering.
I have measured actual volatge which are applied to board is 3.3 V with 70 to 80 mAmp Power. So, Board is restarted in any Wifi Mode with default AT 0.50 Firmware.
I have also compiled AT firmware in NON OS SDK and updated firmware in my Wifi Module but problem remains same in that firmware as well.
Let me know if anyone has any clue or idea for this type of issue.
