I have a Wifi LoRa V2 board which was sending data every 10 minutes. Everything worked fine for a while but then the board stopped sending data. I hooked it up to the PC to check debug information on the serial monitor and all I get is:
10:32:02.290 -> rst:0x10 (RTCWDT_RTC_RESET),boot:0x13 (SPI_FAST_FLASH_BOOT) 10:32:02.290 -> flash read err, 1000 10:32:02.290 -> ets_main.c 371 10:32:02.656 -> ets Jun 8 2016 00:22:57 10:32:02.656 ->
I tried to upload my sketch again but get the following messages:

Is there a way to get my board working again ?
Thanks in advance…
