I've LE910-EUG that communicates with a HTTP web service
successfully but sometimes when the microcontroller sends the AT#HTTPSND
command to the module, the module returns OK directly, if I ignored it
and resend again the command, the module returns to me half the command
string and stops accept AT commands, then I tried to wait for 1 second
then resend again, the module returns a strange character over the PC
terminal and stops receive AT commands.
How can overcome this step without restarting the module via unconditional shutdown pin?
