Module software configuration:
PC connection module serial port RX0, TX0. The default model rate is 9600, stop bit 1, even parity.
Module operation mode:
When the module is powered on, it automatically enters the low-power operation mode. When the CPU is idle, it automatically shuts down, but the peripheral and IO ports are unchanged. Serial input AT command can wake up the CPU immediately, respond and process the command. After the task is processed, the CPU goes to sleep.
Try to enter a low-power sleep state when the CPU is idle. Low current operation is less than 350uA. Enter the command to enter deep sleep mode: AT + MODE = 1, at this time the power consumption reaches the minimum, and the current is 0.7uA. At this time, the timer is turned off, the module cannot perform any work, and the wake-up method: input arbitrary data into the serial port. AT + MODE = 2000, the module enters deep sleep mode, but when the timer is turned on, it will automatically wake up after 2000 milliseconds. At this time, the module current is 1uA. Can also actively wake up: input arbitrary data to the serial port.
Frequently Asked Questions:
Q: What is Ra-06 interface, SPI or UART?
A: Ra-06 is UART interface, Ra-01 & Ra-02 is SPI interface
Q: Can the MCU in Ra-06 be used to develop sensors?
A: Temporarily does not support secondary development
Q: Can Ra-06 communicate with Ra-01?
A: As long as the parameter settings of the two are correct, they can communicate with each other.
Q: Why is the power consumption difference between Ra-06 and Ra-01 / 02 in standby mode so much?
A: Ra-01 and Ra-02 have substrate current, Ra-06 has been improved from the original
Q: Can Ra-06 work with LoRaWAN gateway? Is Ra-06 only capable of point-to-point transmission?
A: Can not be used together. Ra-06 can be used for point-to-point communication, or use a Ra-06 as a gateway.
