)
Code:
[1Bh] + [6Fh] + n

Disabling/enabling PAIRING info saving in Bluetooth mode (
ESC pair=
)
Code:
[1Bh] + [70h] + [61h] + [69h] + [72h] + [3Dh] + n
Possible values of
n
:
‘
0
’: Disables PAIRING info saving.
‘
1
’: Enables PAIRING info saving.
After PAIRING info saving no password is required when making new
Bluetooth
connection, but only
paired devices can communicate. If an old connection (pairing) was saved, it will be destroyed and first
new connection will be saved in it’s place.
After executing this command with argument ‘
0
’ the current saved information will be destroyed, but no
new connection will be saved. Every time a password will be required. The printer will work with all
Bluetooth
devices.
After the command the printer must be switched off (using
ON/OFF
button
or
ESC x
command). The
Bluetooth
connection will be reinitialized the next time the printer is switched on in
Bluetooth
mode.

This command changes the Bluetooth module PIN.
d
contains the new PIN. PIN length is from 0 to 16 characters, allowed are digits and capital latin letters.
The string ends with 00h (ASCIIZ). If the length is 0, Bluetooth module uses no password (PIN).
