As don't have any spares decided to use some ESP12E modules i have.
WEMOS was controlling the roomba (arduino ide code below)
Question is. For WEMOS it was TX and RX pins in the code
#define SERIAL_RX D5 // pin for SoftwareSerial RX
#define SERIAL_TX D6 // pin for SoftwareSerial TX
Do i understand correctly that for ESP i just change to 12 and 14 respectively?
Also found a lot of manual on the wiring to flash (and flashed successfully) but can't find on the minimal wiring after flashing to get it working
