5.6.4 Notes for AUX

No.

Description

For function 1 & function 2 mentioned above, the priority should be given to the one with low level output, which

means if it meets each of any low level output condition, AUX outputs low level, if none of the low level condition is

met, AUX outputs high level.

When AUX outputs low level, it means the module is busy & cannot conduct operating mode checking. Within 1ms

since AUX outputs high level, the mode switch will be completed.

After switching to new operating mode, it will not work in the new mode immediately until AUX rising edge lasts for

2ms . If AUX stays on the high level, the operating mode switch can be affected immediately.

When the user switches to other operating modes from mode 3 (sleep mode) or it’s still in reset process, the module

will reset user parameters, during which AUX outputs low level.

6 Operating mode

There are four operating modes, which are set by M1 and M0, the details are as follows:

Mode（0-3）

Mode introduction

Remark

0 Normal

UART and wireless channel are open, transparent

transmission is on

The receiver must work in

mode 0 or mode 1

2 Wake up

UART and wireless channel are open, the only

difference with mode 0 is that before transmitting data,

increasing the wake up code automatically, so that it can

awake the receiver under mode 3.

The receiver could be 0,1

or 2

3 Power

saving

UART close, wireless is under air-awaken mode, after

receiving data, UART open and send data.

transmitter must be mode 1,

unable to transmit in this

mode.

4 Sleep

sleep mode, receiving parameter setting command is

available.

specification.

6.1 Mode switch

 The user can decide the operating mode by the combination of M1 and M0. The two GPIO of MCU can be used to

switch mode. After modifying M1 or M0, it will start to work in new mode 1ms later if the module is free. If there
