Hello JH If SerialOptions defaults (parity, csize, flow, stop) are good for you SerialOptions() : device(), baudrate(9600), timeout(seconds(0)), parity(noparity), csize(8), flow(noflow), stop(one) {} then try to add \r to the end of your AT command - serial<<"AT+CGDCONT?" << endl;. + serial<<"AT+CGDCONT?\r\n"; 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. вт, 14 янв. 2020 г. в 02:34, JH <jupiter.hce@gmail.com>:
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,

Hi,
There are many boost serial port sample code out there, but none of them I can run AT command. I have a device connected to my ubuntu 18, I can run AT command on minicom to get correct response, but I could not get any AT response from boost serial port. Has anyone made it work?
Thank you.
Kind regards,

Could you please show the code? Just guess, incorrect baud rate or other config parameters (ref. https://www.boost.org/doc/libs/1_72_0/doc/html/boost_asio/reference/basic_se...)
