5.8 Module reset
Reset using the hardware NRST pin. The built-in MCU needs to be pulled down for at least 10 ms before
being released to reset the MCU.
Using MODBUS command to reset (01 06 07 EA 5B B5 53 CD), that is, write 0x5bb5 to register 07ea
h to enter watchdog reset, and the module will restart after a period of time.
5.9 Aux details
Aux will be pulled down in the following cases:
P
ower on and enter the initialization process
D
ata received through serial port
Serial port is sending data
RF is sending data
S
aving data to flash
5.9.1 Serial port data output indication
W
hen UART needs to send data, aux will be pulled down about 5ms in advance to wake up the external
MCU in sleep.
When the module receives the RF signal, it will delay about 10ms to wait for the sending module
to be ready, and then reply through Lora or UART.
When data is received at RF and needs to be output through UART, a delay of 15ms will pass.
5.9.2 Work instructions
when UART receives the non local MODBUS command or the first byte of the non MODBUS command, aux
will be pulled down until RF transmission is completed.
