Re: Lolin C3 problems
You can't, must be done in the firmware.
Try this one, should work for you (without H/W changes)

Re: Lolin C3 problems
Still the same - reports flash success, but no SSID available.
Just to confirm, was 1.50.1, flashed in USB mode using QIO with button held in continuously.

Re: Lolin C3 problems
Probably you should also make the H/W modification.
I soldered back the capacitor and mine still works

Re: Lolin C3 problems
Can you confirm that you flashed with USB mode even though the device has serial uart and automatically reports device id from blue button in normal (not USB) mode ?

Re: Lolin C3 problems
This module does not have a USB to serial chip, the USB is supported by the chipset itself.
You can see that in the module schematic :
https://www.wemos.cc/en/latest/_static/ ... v1.0.0.pdf
The version you loaded is the good one, you could just confirm what you have in the serial terminal.
Use the web terminal [Local Link Removed for Guests] because the one included in the toolkit do not works properly with these chips.

Re: Lolin C3 problems
There is actually a statement about the power setting on the manufacturer's website (about halfway down the page).

The later version seems to include a low value choke and an extra capacitor on the 3.3 volt supply.

Re: Lolin C3 problems
I see that there is an extra inductor on the pin 2-3 but, anyway, the antenna is completely different.
It costs around 1€ more and it includes a neopixel led.
