Have OH3 M5 running on a Ubuntu server. And have a SMS modem on /dev/ttyUSB2 port.
Installed the serial Binding and sending and receiving from the modem works well. But i do not know how to send the ctrl+Z command wich is needed to close the AT+CMG command (send sms).
Have tried:
What do you mean the binding could not parse the \x, do you mean the binding is sending the string \x1A rather than the byte value 26?
How are you trying to send those item commands, is it a rule configured through the UI? If so are you able to look at the rule in the JSONDB and see how many \ characters are before the x
