Re: [boost] Anyone got AT commands work using asio serial port?

Hi Sergei.

I know for a fact that asio serial is objects work fine.

Please post a minimal complete program that demonstrates how you are using asio to communicate with the serial port.

The problem will certainly be there.

Hi,

It looks going no way to get it work, I have to find a consultant for helping me to get it work, anyone interested, please contact me privately, I'll pay your full service if you could deliver me a working serial command source to run AT command.

Thank you.

Kind regards,

Hello JH

If SerialOptions defaults (parity, csize, flow, stop) are good for you

Yes, I was using all defaults, that should work right?

...

SerialOptions() : device(), baudrate(9600), timeout(seconds(0)), parity(noparity), csize(8), flow(noflow), stop(one) {}

The only different was I set baudrate to 115200, I changed to use 9600, doesn't seem work either.

...

then try to add \r to the end of your AT command - serial<<"AT+CGDCONT?" << endl;. + serial<<"AT+CGDCONT?\r\n"; I did try to add "\r\n", no avail.

Hmm, did not realize boost serial port is that hard, any working boost serial port samples online?

Thank you.

Kind regards,

AFAIR, AT commands, use it as line end (ref https://en.wikipedia.org/wiki/Hayes_command_set), but on Linux std::endl only LF(0x0A). Maybe this is your case. HTH.

Hi Sergei,

Thanks for your response.

Please find code I found from Internet attached, the same baud rate, serial port and AT command I can get response from minicom, but empty response from the boost serial port, I don't think it was the baud rate issue or option parameters issue, but I could be wrong.

Appreciate if you could get it work.

Thank you.

Kind regards,

Hello, Richard. I have no problems with serial ports. Could you please re-read whole email thread? You'll also find code from JH, who original topic starter. --
