2.8 SPP – Asynchronous Messages
RING
This string is sent to the host when a remote device is initiating a serial port connection. The fully
qualified string is in the form RING 012345678901 where 012345678901 is a 12 digit hexadecimal
number which corresponds to the remote device’s Bluetooth address. This response is sent to the
host every 2 seconds until the host either accepts the connection using the ATA command or rejects
it using the ATH command.
CONNECT 123456789012,1101,<
An SPP connection has with Bluetooth device 123456789012 has been established successfully.
The connection was initiated by the remote device (incoming).
CONNECT 123456789012,1101,>
An SPP connection has with Bluetooth device 123456789012 has been established successfully. The
connection was initiated by the local device (outgoing).
2.9 SPP – S Registers
S Registers for SPP are summarized in Table 3-17 below.
Table 3-17: S Registers for SPP
Register Default Range Description
S0 0 -1..15 Number of RING indication before automatically
answering an incoming connection. A value of 0
disables autoanswer. If -1, then autoanswer on one RING
and do NOT send RING/CONNECT response
to the host. This emulates a serial cable replacement
situation Setting values >= 0, resets S Register 504 to 0 and
<0 forces 504 to 1.
If S0 <> 0 and S100 <> 0 then S0 must be < S100. If a value
is entered which violates this rule, then ERROR 29 is sent in
response.
If S504 =1 then this register will return -1, regardless of the
actual value stored in non-volatile memory.
S100 15 0..15 Number of RING indications before an auto
disconnection is initiated. A value of 0 disables
this feature. If S0 <> 0 and S100 <> 0 then S0
must be < S100. If a value is entered which violates this
rule, then ERROR 29 is sent in response.
