OnCell G2150I AT Command Set AT Command Features
2-2
Serial Line Settings
A serial link handler is configured with the following default values (factory settings):
y 115200 bps
y 8 data bits
y 1 stop bit
y no parity
y RTS/CTS flow control
Use the +IPR, +IFC, and +ICF commands to change these settings.
Command Line
Commands always start with AT (which means ATtention) and finish with a <CR> character.
Information Response and Result Codes
Responses start and end with <CR><LF> (except for the ATV0 DCE response format) and the
ATQ1 (result code suppression) commands.
y If the command syntax is incorrect, the “ERROR” string is returned.
y If the command syntax is correct, but the command is transmitted with the wrong parameters,
the +CME ERROR: <Err> or +CMS ERROR: <SmsErr> strings are returned with adequate
error codes if CMEE was previously set to 1. By default, CMEE is set to 0, and the error
message is only “ERROR.”
y If the command line has been executed successfully, an “OK” string is returned.
In some cases, such as “AT+CPIN?” or (unsolicited) incoming events, the product does not return
the “OK” string as a response.
In the following examples <CR> and <CR><LF> are omitted intentionally.
