Settings tool. Once the output of EXT_CLK signal is enabled, most other
commands will return error until the output of the EXT_CLK signal is
disabled.
It should also be noted that UART Flow Control (RTS/CTS) cannot be
enabled when enabling the output of EXT_CLK due to the multiplexing of
the GPIO2 pin. If UART Flow Control (RTS/CTS) is enabled and this
mode is enabled, an error will be returned.
Finally, once the correct RXTUN value is determined, it needs to be set
programmed into the Factory settings information, or programmed
dynamically with the Dynamic settings command ( AT+BTSET ). Until the
RXTUN value is programmed into the Factory or Dynamic settings it will
not be used by the 1SPP firmware for Bluetooth operation (once this
command is complete).
Format:
AT+BTRXT=<X>, <Y>
where,
<X> is a single ASCII digit:
0 – disable output EXT_CLK signal on GPIO2
1 – enable disable output EXT_CLK signal on GPIO2
<Y> is either an integer value (0 -255) or a hexadecimal value
(0x00 – 0xFF) which represents the RXTUN value to use. This
parameter is optional when enabling the output of the EXT_CLK
and is ignored when disabling the output of the EXT_CLK
or one of the following to query the current RXTUN calibration mode
value:
AT+BTRXT?
AT+BTRXT
Results:
If a query is performed, the output will be the following format:
+BTRXT: <X>
where,
<X> is a single ASCII Digit:
0 – output of EXT_CLK signal on GPIO2 is disabled
1 – output of EXT_CLK signal on GPIO2 is enabled
Immediately following the above output, the response will be the result
code (either OK or ERROR ).
If a query was not performed (i.e. the test mode was set) then the result
will simply consist of the result code (either OK or ERROR ).
