SIM868 - how to disable verbose/debug mode(?)

[twizzter]

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:

Code: [Select]

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:

Code: [Select]

1958-01-01 11:08:55[0][D][socket.c:236 bear_notify_cb]bear_notify state: CBM_DEA
CTIVATED.

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?

That second output log doesn't look like SIM8xx output. Is there a secondary controller inbetween?

I'm hooked up to the module's UART1. Attached a photo of PCB and a schematic for reference.

It's a while since I used SIM868 but I don't recall the output being so verbose.
There is a command ATV that relates to the response format, you an also turn off echo with ATE.
You will have to write a parser anyway, so you will become very familiar with the command set:

One other point, SIM868 is 2G only, which will be sunset pretty much everywhere in 5-10 years, perhaps sooner in some regions, already done in some. It might be better to learn how to work with an NB-IoT or CATM module.
