5.3.15 Factory Default (Preserve Protocol Setting)
Command:
AT&F*AT*
Response:
<cr,lf>OK<cr,lf>
Or
<cr,lf>ERROR nn<cr,lf>
Description:
This command erases all user parameters in non-volatile memory except S Register
9255. This means that the trusted device database clears, but ‘AT’ protocol mode
retains and UART parameters reset to factory default settings.
The new protocol and settings become active after a reset.
5.3.16 Factory default (Full, then change into MP mode)
Command:
AT&F*MP*
Response:
<cr,lf>OK<cr,lf>
Or
<cr,lf>ERROR nn<cr,lf>
Description:
This command erases all user parameters in non-volatile memory including S Register
9255 and S Reg 9255 is set to 1 for MP mode. This means that the trusted device
database clears, and protocol sets to MP mode and all UART parameters are reset to
factory default settings.
The new protocol and settings become active after a reset.
5.3.17 Write S Registers To Non-Volatile Memory
Command:
AT&W
Response:
<cr,lf>OK<cr,lf>
Or
<cr,lf>ERROR nn<cr,lf>
Description:
Writes current S Register values to non-volatile memory so that they retain over a
power cycle.
5.3.18 Write <String> To Blob(0)
Command:
AT+BTB=<string>
Response:
<cr,lf>OK<cr,lf>
Or
<cr,lf>ERROR nn<cr,lf>
Description:
This command clears BLOB(0) first and then <string> appended to that BLOB after the
string de-escapes. This allows binary data to load into the BLOB buffer for
subsequent processing using the AT+BTBnnnn command syntax.
