Chapter 6 Work Modes
6.1 Mode switching
The user can combine the high and low levels of M2M1M0 to determine the module operating mode. The MCU's GPIO
can be used to control mode switching; When changing M2M1M0: if the module is idle (AUX high), it can start working
according to the new mode; If the module has serial port data that has not been transmitted wirelessly, it can enter the
new working mode only after the transmission is completed; If the module receives wireless data and sends out data
through the serial port, it needs to be sent before it can enter the new working mode; So the mode switch can only
be
used when
AUX outputs
1
, otherwise the switching will be delayed.
For example, in mode 2 or mode 4
, the
user continuously enters a large amount of data and switches the mode at the
same time, and the switching mode operation is invalid; The module will process all user data before performing new
pattern detection; Therefore, the general recommendation is: detect
the
AUX pin output status, wait for the AUX output
high level and
then switch for
2ms.
When the module is switched from other modes to configuration mode, if there is data that has not been processed; The
Mode (0-7).
