We had issues with PR58-1_MQTT always falling back to DHCP. We found here that it was a known issue and to upgrade the firmware. We updated to 1.0.4 to get the latest which did not solve the problem. I then tried to get bac kto 1.0.2 which in the Repo had the resultion in the PR. I was able to downgrade the firmware but got a crash during the upload of the spiff file.
Now, the device has a red blinking status and no way to connect to its wifi, or on our wifi. I tried to get into the COM port but i dont have the files to inject in it.
Seems like its pretty dead to me.
If i hold the reset button - Nothing
If i do the power cycle with the CFG button i see a half blue half RED LED but then goes back to a flashing RED LED.
Please help.
If the SPIFFS upload failed then the SPIFFS file would need to be uploaded manually over the USB connection. That’s a bit complex. Do you want me to attempt providing instructions on how to upload SPIFFS over USB or do you simply want to send it in for RMA?
If you can send me the instructions that would be amazing, then I’ll send it over if it fails.
Many thanks!
Ok. Here’s the steps:
You’ll need to install this driver to mount the board to your computer:
Next you’ll need download esptools:
https://docs.espressif.com/projects/esptool/en/latest/esp32/
Then you’ll need to run this from the command line:
python esptool.py -p COMX -b 460800 --before default_reset --after hard_reset --chip esp32 write_flash --flash_mode dio --flash_size detect --flash_freq 40m , 2691072, spiffs.bin
You may need to replace python with python3 depending on what is currently installed. Also COMX should be replaced with the COM port the module mounts to on the OS such as COM1, COM2, etc.
Seems like it did something, now i have the blue LED and red LED lit up. After 5 minutes went back to red flash…

What happens if you press the CFG button? Does the LED flash Blue and allow you to connect to it directly over WiFi?
The LED turns off then goes back to flashing red …
