I would like to ask what is the correct action after CME error socket opening timeout was received. Should I send escape sequence (+++) or assume that the modem is still in command mode and continue without esc. sequence?
Actually after any error following AT#SKTD.. or should the esc. sequence be used only after successfull connection has been established (marked with CONNECT)
The escape sequence should be used only in data mode, ie after connection is established. If timeout occurs is evident that the interface is in command mode, no connection is active, so nothing to terminate.
