ESP32-WROVER-V4 won't recieve commands over uart
Posted: Fri May 04, 2018 8:41 pm
I am pretty sure i have burned somthing but i would like a second opinion, if you can point me at anywhere i would be gratefull
Here is a photo of my setup
The arduino on the left is one of those cheap ones with the CH340 instead of the FTDI chip but it seems like it is working.
When i bridge TX+RX i get my message sent back as a responce so the TX + RX should be working, at least until the arduino
The RX part of the arduino and the TX part of the ESP32 are working nicely
With EN high
With EN floating
With EN high and IO0 low
**keep in mind that when i send a command from terminal the green light of the TX on the arduino lights up.
Looking forward to your advice

The TX goes from the arduino to 150 Ohm resistor to a 300 Ohm resistor with the cable in the middle going to the RX of the ESP32 as a voltage divider (the resistors in the photo do not have the correct value but i have replaced them since)rst:0x1 (POWERON_RESET),boot:0x23 (DOWNLOAD_BOOT(UART0/UART1/SDIO_REI_REO_V2))
waiting for download
**keep in mind that when i send a command from terminal the green light of the TX on the arduino lights up.
Looking forward to your advice
