I recently bought a cactus r2, fast shipping really nice. I made some test and all was fine until I changed the esp baud rate.
I wanted to use espduino, when trying to run the esptool, I always had a “Failed to connect”. esptool use a baud rate of 115200, the esp8266Programmer use a baud rate of 115000.
I managed to run the searchBaudRate sketch, it told me that the baud rate of the esp was 9600. So I tryed to the hardwareSerialMonitor at 9600 and it was working. Even so, I didn’t get the esp to connect to my wifi with AT command.
Back to the esptool, I tryed to set the baudrate of the esp to 115200 with “AT+CIOBAUD=115200”, it replies OK. And then I was unable to communicate at 115200, so I tryed again the searchBaudRate and now it said “not found”.
Bricked or not?
