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.

Aux will be pulled down in the following cases:



ower on and enter the initialization process

ata received through serial port



Serial port is sending data

RF is sending data



aving data to flash





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.

 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.
