Description
Enable Extended Sdp Error Codes
0 - disable
1 – enable
Enable silent operation:
Setting to 1 will force S0 to -1 and will suppress messages arising
from connections or pairing. E.g., CONNECT, NO CARRIER, RING,
PAIR, etc.
Suppressing connection based messaged allows the device to be
configured in cable replacement mode.
Minimum delay before abandoning connection attempt as a
master.
Referenced by ATD. In units of seconds. See S Registers 530 and
543 also. Please note that as disconnection time can vary, this
register only guarantees the minimum delay. Note that for invalid
addresses specified in the ATD command, the “NO CARRIER”
response will be immediate. See S register 560 for specifying dis-
connect max timeout.
Enable/Disable echoes. The ATEn command also affects this.
When set to 0, a connection can be dropped using ^^^ escape
sequence only and the state of DSR line is ignored.
When set to 1, a connection can be dropped using EITHER the
^^^ escape sequence OR the DSR handshaking line. When set
to 2, a connection can only dropped using a deassertion of DSR.
Mode 2 provides for the highest data transfer rate.
If the status of the DSR line is to be conveyed to the remote device
as a low bandwidth signal then this register MUST be set to 0,
otherwise a deassertion of DSR will be seen as a request to drop
the Bluetooth connection. This register affects S Register 536 – see
details of 536.
Page Scan Interval in milliseconds. Minimum is 11.25ms so
10/11ms will give 11.25ms, refer to Section 7, page. 93.
Page Scan Window in milliseconds. Minimum is 11.25ms so
10/11ms will give 11.25ms, refer to Section 7, page. 93.
Inquiry Scan Interval in milliseconds. Minimum is 11.25ms so
10/11ms will give 11.25ms, refer to Section 7, page. 93.
