Hello George,

Something is very wrong! Before we discuss how to solve that could you do this test?

1) Remove the Esp32 module from its socket
2) With an USB cable power the module from a PC or from a phone charger
3) Press and Hold for about 3 seconds the button "Boot" and then release it
4) Check if the Nmea4Wifi network is created

I wait for your feedback

Regards, Luis

Dear Luis,

Yes, I tried this process, but looks like there is no communication. I tried with Arduino IDE because I can check it with this, if I push the reset button, on the screen I can check the reset process, but there is nothing happened. :-(

Hello,

After the last post on this topic I exchanged private emails with George. We came to the conclusion that the problem was with the ESP32 module. George was used to Arduino and tried to flash it but with no success. I sent him a new multiplexer and he returned back to me the old one. By some reason, the serial interface on the module was not working. I sent the module to the waste bin. It was the first time such a problem happened. Since 2 weeks have passed and I did not hear from George, I assume the multiplexer is now working as expected.

Regards, Luis

Hello,

Please describe better the problem as I could not understand the 12V measurement that you refer to.

Hello Didier,

Do you mean that nothing happens? Does the voltage regulator works? The voltage regulator is a small red pcb with a red light. Is that red light on? Please clarify.
