7.1 AT commands
7.1.1 Syntax of Standard AT Commands
The AT standard is a line-oriented command language. Each command consists of three
elements: Prefix, body and end character.
The prefix always consists of the letters “AT“.
The body consists of a name and pertinent values, if applicable. If a pertinent value is
optional, this is indicated by square brackets ([...]).
The end character is <CR> (=0X0D) by default.
Commands can be grouped to one command line. Space characters between the
individual main parts are ignored. The commands can be categorized as follows:
• Basic instruction set
• Extended instruction set (Main part starts with “+” or “^”)
The commands are acknowledged with “OK” or “ERROR”. A command that is being
edited will be interrupted by any further incoming character. Therefore, the next
command must wait for acknowledgement to avoid the deletion of the current
command.
7.1.2 Overview AT Commands
Command Description
ATA
Manual connection acceptance
ATA accepts an incoming connection.
ATA only works when the model previously received packets at the local port, i.e. issued
the command „RING“.
AT#APD= AP Density
Setting the search algorithms to AccessPoints – depending on the density of the
AccessPoints that is to be expected:
AT#APD=1 "Large Density"
AT#APD=2 "Medium Density"
AT#APD=3 "Small Density" (default)
AT#APD=4 "Mini Density"
AT#APD=5 "Micro Density"
The setting AT#APD is immediately stored in the permanent memory (independent from
the command AT&W). The setting will only take effect with Reboot (AT#RBT).
