Monitor Address; Reset; Aux Description; Indication Of Uart Output - Ebyte E32-400T20S User Manual

Chengdu Ebyte Electronic Technology Co,;Ltd
When module is the transmitter (transparent transmission), all modules under channel 0x04 will receive the data, the

purpose of broadcast is realized.

5.4 Monitor address

For example: Set the address of module A as 0xFFFF, and the channel as 0x04;

When module A is the receiver, it can receive the data sent from all modules under channel 0x04, the purpose of

monitor is realized.

5.5 Reset

When the module is powered, AUX outputs low level immediately, conducts hardware self-check and sets the operating
mode based on user's parameters. During the process, the AUX remains low level. After the process completed, the AUX
outputs high level and starts to work as per the operating mode combined by M1 and M0. Therefore, users need to wait
the AUX rising edge as the start of module's normal work.

5.6 AUX description

AUX Pin can be used as indication for wireless send & receive buffer and self-check.

It can indicate whether there are data that are not sent yet via wireless way, or whether all wireless data has been

sent through UART, or whether the module is still in the process of self-check initialization.

5.6.1 Indication of UART output

To wake up external MCU


5.6.2 Indication of wireless transmitting

Buffer (empty): the internal 512 bytes data in the buffer are written to the RFIC (Auto sub-packaging).

When AUX=1, the user can input data less than 512 bytes continuously without overflow. Buffer (not empty): when
