New WEMOS D1 Pro Mini arrived today, from a different supplier.
I converted it to ext. antenna as instructed by @irukard .
I ran a two tests to check the WiFi. It will scan for networks and act as an access point. So the antenna is working.
I hooked up the BME280 to D3 & D4 and it worked OK. Phew…
I assembled everything back into the box.
Note all the wiring is soldered directly to the MCU.
Next I flashed the MCU with the airRohr code, latest_en.bin
No Access Point.
I then reprogrammed the MCU with the test Access Point code from the Arduino IDE and all is good, it produces an AP.
So then I hit ‘Erase Flash’ then reflashed with airRohr firmware.
No Access Point.
I also performed the above with the Old WEMOS that would not read the BME280 and it produces an Access Point etc. So I know my technique is Ok. I just cant get the new WEMOS to produce an Access Point.
Any ideas please?
