Reading ascii serial communication with from Nextion display #5774

Closed andreapede closed 5 years ago

andreapede commented 5 years ago
### ISSUE DESCRIPTION - TROUBLESHOOTING Nextion display send data via serial port using ascii string that ends with a triple ansi code delimiter \xFF\xFF\xFF. To send data to the nextion the procedure is the same and it is necessary to send a string ending with the same three escapes code. I can send the data (just fixed the last bugs) using the SerialSend3 command that accepts the 3 escape code at the end. I can also read the incoming message from Nextion display in hex from Tasmota firmware, but only if I use, triggering the routine, the SerialCommand5. In this way the esp8266 start receiving information in hex, otherwise there is no effect. ### REQUESTED INFORMATION Due to the fact that I use node-red flow to send and receive the data, sending a message using the SerialSend3 and after that another SS5 is quite tricky. Also it does seems to me that a proper reception should be independent from this sort of triggering. Something to suggest or is it a bug? **FAILURE TO COMPLETE THE REQUESTED INFORMATION WILL RESULT IN YOUR ISSUE BEING CLOSED** - [ x] Read the [Contributing Guide and Policy](https://github.com/arendst/Sonoff-Tasmota/blob/development/CONTRIBUTING.md) and [the Code of Conduct](https://github.com/arendst/Sonoff-Tasmota/blob/development/CODE_OF_CONDUCT.md) - [ x] Searched the problem in issues (https://github.com/arendst/Sonoff-Tasmota/issues) - [ x] Searched the problem in the wiki (https://github.com/arendst/Sonoff-Tasmota/wiki/Troubleshooting) - [ x] Searched the problem in the forum (https://groups.google.com/d/forum/sonoffusers) - [ x] Searched the problem in the chat (https://discord.gg/Ks2Kzd4) - [ x] Device used (i.e. Sonoff Basic) : 18 Generic - [ x] Tasmota binary firmware version number used : 6059/ self-compiled ?

I suppose I must try to use directly the SerialSend5 to transmit and recive all the data.

Just discovered the the flag mqtt_serial_raw flush out all the ascii code > 127 if set to 0 (as in the SerialSend3) and the reason for not reciving the string from Nextion (that contains the escape codes).
