6. Operating mode
The module has four operating modes, which are set by pins MO and M1; details are shown in the table below.

6.1 Mode switching
®
Users can combine MO and M1 with high and low levels to determine the operating mode of the module. Users
can use the MCUs 2 GPIOs to control the node switching; after changing M0,M1: the module is idle and after
Ims, it can start working according to the new operating mode; if the module has not transmitted serial port
data via wireless, then entering the new
operating mode
after the transmission
completed;
if the module
receives the wireless data and sends out the data through the serial port, it needs to finish sending before
entering the new operating mode;
if the module;
so the mode
switching can only be effective when AUX
outputs 1, otherwise the switch will be delayed.
®
For example: In mode 0, the user continuously inputs a large amount of data and switches the mode at the
same time. The mode switching operation is invalid at this time; the module will process all the user data
before performing the new mode detection; so the general recommendation is: Detect the AUX
pin output
status, wait for 2ms after the AUX output goes high before switching.
®
When the module is switched from other modes to sleep mode, if any data has not been processed, the module
will enter the sleep mode after processing the data(including
receiving and
sending). This feature can be
used for fast sleep mode to save power consumption; for example: the transmitter module works in mode0, the
user initiates serial data "12345" and then does not have to wait for the AUX pin to be idle (high level ),and can
directly switch to sleep mode, And the user's main MCU will immediately sleep, the module will automatically
send all user data through wireless, and automatically enter sleep within 1ms; thus saving the MCU's working
time and reducing power consumption.
®
Similarly, any mode switch can use this feature.
After processing the current mode event, the module will
automatically enter the new mode within 1ms; thereby eliminating the user's query of AUX and achieving the
goal of fast switching ,For example, switching from the transmission mode to the setting mode; the user MCU
can also go to sleep mode in advance before the mode switching,
and use the external interrupt function to
