The GPIO16 is wired to pin RESET. It cause you can’t programming directly. Please short the VCC and RST at USB to UART converter first and upload firmware.
Dear aprilpea,
I wired the VCC and RST at the USBtoUART in order to short them. However I am still getting the same result. There is not way to transfer the code at the ESP82666. Apparently the ESP8266 is not waking up. Do you have any idea?
I tried on my MacBook Air and in a PC, with the same result.
Below you can see the error message:
Many thanks in advance,
Miguel
There is not way to connect. I exported the bin file and using the modemcu-flasher software I got the same result.
I connected the hardware as I showed and I don’t get the MAC address. At the modemcu-flasher software when I press flash button is waiting without any answer. I tried to update the bin file without success.
What could I do it?
I bought 2 soil moisture sensor and 2 ESP8266 Flasher, and either of them works, could I update to one of the new sensor version with a discount?
Thanks in advance
Miguel
