AT COMMAND SET
REFERENCE
AT Commands for a Selected Peer Device
This section describes AT commands to make the BTM Bluetooth device connectable for one particular
remote device only or to connect to a particular remote device on reset or on power cycle
automatically.
1.
AT+BTP<bd_addr> {Make Device Discoverable and Selectively Connectable}
Make the BTM device discoverable (for all devices) and connectable for the device with the
Bluetooth address <bd_addr> only. Connection requests from any other devices will be rejected.
If <bd_addr> is 000000000000 then incoming connections are accepted from any device, as per
AT+BTP without an address.
The setting remains valid until next reset or power cycle (unless not changed by any other AT
command subsequently). For permanent discoverable/connectable settings, please refer to S
Register 512 and AT+BTM<bd_addr>
Response:
<cr,lf>OK<cr,lf>
2.
AT+BTG<bd_addr>
{Make Device Selectively Connectable Only}
Make the BTM device connectable for the device with the Bluetooth address <bd_addr> only.
Connection requests from any other devices will be rejected.
If the specified address is 000000000000 then incoming connections are accepted from any device,
is as per AT+BTP without an address.
The BTM device is not discoverable.
The setting remains valid until next reset or power cycle (unless not changed by any other AT
command subsequently). For permanent discoverable/connectable settings, please refer to S
Register 512 and AT+BTM<bd_addr>
Response:
<cr,lf>OK<cr,lf>
3.
AT+BTM<bd_addr>
{Set Incoming Peer Address}
This command is used to store a peer address for incoming connections in non-volatile memory.
Only the device with Bluetooth address <bd_addr> will be permitted to make a connection to the
BTM device. Connection requests from other devices will be rejected.
The new setting applies immediately and will retain over a power cycle (unless not changed by any
other AT command subsequently).
When S register 512 = 3, 4, 6 or 7 then the BTM device will wait for an incoming connection from
the peer address specified. If <bd_addr> is 000000000000, then incoming connections from any
devices are permitted.
Response:
<cr,lf>OK<cr,lf>
4.
AT+BTM
{Delete Incoming Peer Address}
This command is used to delete the peer address previously stored using AT+BTM<bd_addr>.
If the BTM device was connectable for the selected device before this command, it will be
connectable for any device immediately after this command.
Response:
<cr,lf>OK<cr,lf>
