Is there an AT command or config option that will mute the module to send only the most relevant information over the UART?
For example, if I send "ATI" the module returns a lot of useless information:
1958-01-01 11:02:46[0][D][uart.c:43 event_uart_ready_rd]uart 0 recv: ATI
modem recv: ATI
SIM868 R14.18
0
Plus the console throws randomly:
1958-01-01 11:08:55[0][D][socket.c:236 bear_notify_cb]bear_notify state: CBM_DEA
CTIVATED.
1958-01-01 11:09:00[0][D][event.c:70 event_timer]timer TIMER_MAIN_LOOP happened.
1958-01-01 11:09:00[0][D][gps_utils.c:177 gps_getGPS]gps status NOT FIXED, pleas

Not sure if it's important, but module was bought as an evaluation board from Ali.
It turned out that module's sticker has been covered with a new one having different IMEI. I guess recycled component? Beta/buggy/improper firmware maybe?
