No Wifi AP on first boot #53

Dear,

I bought the v5.2 from Elecrow. https://www.elecrow.com/ebus-to-wifi-adapter-module-v5-2.html

Documentation stated that it should just be plug and play.

I connect the module to the eBus and LEDs start flashing. However the Wifi AP never appears, so I don't have any option to configure the module. I suspect the firmware is not flashed or not properly flashed.

I tried reflashing with an UART USB adapter. But I never can seem to get the module in programming mode. NodeMCU PyFlasher only shows Connecting ...___... Can you please advise on how to connect the PROG pin? Should it just be set to GND?

Thanks

Hi @vermmatt , yes, just connect PROG and GND before connecting the adapter to USB.
