Bhe Chengdu Ebyte Electronic Technology Co,Ltd E32-433T30D user manual
purpose of broadcast is realized.
5.4 Monitor address
® For example: Set the address of module A as OxFFFF, 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 MO.
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
All the wireless data received have been
To wake up the external sent by TXD.(The buffer is actually empty.)
MCU 2-3ms in advance

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
AUX=0, the internal 512 bytes data in the buffer have not been written to the RFIC completely. If the user starts to
transmit data at this circumstance, it may cause overtime when the module is waiting for the user data, or
transmitting wireless sub package.
