Chapter 2 – AT Commands
Multi-Tech Systems, Inc. SocketWireless Bluetooth AT Commands (S000360H) 30
SW29 Write PIN Lock Mode
The command configures the PIN lock setting.
Format: ATSW29,<PIN>,<Lock Mode>
Parameters:
PIN: 16 alphanumeric characters MAX (Caps Sensitive, includes spaces)
Lock Setting:
0 = In Normal operation ATOP is disabled
1 = Allow ATOP through UART only
2 = Allow ATOP through UART and over RF Link
Factory Default: 0
EXAMPLE:
TYPE: ATSW29,default,1<cr>
REPLY: <cr_lf>OK<cr_lf>
OR
<cr_lf>ERROR<cr_lf>
Read Using: ATSI,15
Note: This command enables ATOP, described in the Security PIN Settings section.
SW30 Write Deep Sleep Mode
This command configures the deep sleep mode.
Format: ATSW30,<Deep Sleep Mode>
Parameters:
Deep Sleep Mode:
0 = Normal Operation never go into deep sleep
1 = Go into deep sleep whenever possible (While idle, page scan or sniff mode)
Factory Default: 0
EXAMPLE:
TYPE: ATSW30,1<cr>
REPLY: <cr_lf>OK<cr_lf>
OR
<cr_lf>ERROR<cr_lf>
Read Using: ATSI,16
Notes:
When the radio is in deep sleep you can not discover or connect to it.
The UART RX line needs to be pulled high if not active before power is applied to the
radio module.
If there is an active UART RF link the device will need Sniff Mode enabled to allow it to
drop into sleep mode when there is no traffic.
When in deep sleep, the UART will miss the first character while waking up. Send a
preamble byte to allow it to wake up and immediately thereafter send the AT Command
or data in less than 1 second or the device will go back to deep sleep again. If you are
using PIO(3) CPU interrupt a preamble byte is not needed.
No bytes are lost if sending commands down over the remote RF link side.
This setting is stored in flash and does not require a reset to take affect. Takes approx. 1
second before the current will drop down to 25-50uA. Allow 5msec. for the CPU unit to
come out of deep sleep.
ATSW21,4096,18,4096,18 settings along with enabling Deep Sleep Mode will result in an
unconnected slave current draw of 350uA average.
