ESP32-WROVER-V4 won't recieve commands over uart

Postby Geocheats2 » 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

Image

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
rst:0x1 (POWERON_RESET),boot:0x23 (DOWNLOAD_BOOT(UART0/UART1/SDIO_REI_REO_V2))
waiting for download
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)

**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

I just received a proper CP2102 USB to UART but I still have the same problem ESP32 won't even reply to the AT command :(

At command by default is on uart1 but debug you show is on uart0
