Hello. I got a 8266-equipped system and need to talk to the module - and can't. It runs at 26MHz oscillator, I only have Tx and Rx signals to it. Upon startup it sends the status information at 74880 bps, but when I send "AT\r\n" to it, I get no answer. (Tried also "AT\r", "AT\n", "AT\n\r", no luck.) Connections checked, seem to be OK. UART configured, as I said I can receive the welcome message. Any ideas? Some transparent mode which I don't know how to break? ("+++" does not help.) Some UART parameter change after the startup? (I've tried about 200 speeds from 230400 down and none worked.) Some hardware misconfiguration?
