LoRaWAN built using the RHF76-052 with optional Antennas. RHF76-052 is designed by Ai-Thinker, it is a LoRaWAN ™ UART modem & compatible device, supports LoRaWAN communication. It's based on the RHF76-052 module and an embedded LoRaWAN stack. You can use M5 core as a host MCU to control this this modem with simple AT command or UART.
Since LoRa defines the lower physical layer, the upper networking layers were lacking. LoRaWAN was developed to define the upper layers of the network. LoRaWAN is a media access control (MAC) layer protocol but acts mainly as a network layer protocol for managing communication between LPWAN gateways and end-node devices as a routing protocol, maintained by the LoRa Alliance.
you can upgrade your work with a LoRa / LoRaWAN radio, so it can communicate over very long distances and extremely low power consuming.
By default, the UART configuration: "9600, 8, n, 1"(8 bits data, no parity, 1 stop bit)
Notice: The 5 holes which are under the silk screen "LoRaWAN" are designed for upgrading the firmware of LoRaWAN module.
|Work temperature||-40 ~+85C|
|Storage temperature||-40 ~ +90C, < 90% RH|
1.EasyLoader is a simple and fast program burner. Every product page in EasyLoader provides a product-related case program. It can be burned to the master through simple steps, and a series of function verification can be performed.
2.After downloading the software, double-click to run the application, connect the M5 device to the computer via the data cable, select the port parameters, and click "Burn" to start burning.
3.The CP210X (USB driver) needs to be installed before the EasyLoader is burned. Click here to download driver
M5Stack Fire has occupied GPIO16 / 17 to connect with the PSRAM by default, it's conflict with TXD / RXD (GPIO16, GPIO17) in this module. Therefore, when using the LoRaWAN module with the M5Stack Fire, you might have to cut the TXD and RXD from LoRaWAN module and wire fly to another set of UART pin
This is a exmaple of p2p LoRaWAN modules communication. Reference to
3.6 Point to Point communication with LoRa of
LoRaWAN User Manual
Function: Press button B to set 433MHz as LoRaWAN operating frequency, and send "Hello World"; Press button C to set 868MHz as LoRaWAN operating frequency and send "Hello World"; Press button A to clear the screen.
Execute the following statement in Setup() of the Arduino program
When M5Core2 is stacked with other M5 modules, you need to remove the battery base of Core2, which does not support module stacking.
Reason and solution: The power supply current of the port is insufficient, which can cause the device to not enter the download mode normally. You can try to connect a capacitor (>0.1uF) between the RST pin and the GND pin, or when uploading the program, set the G0 Short-circuit to GND, so that G0 can be set to a low level state normally
Add the header file #include <driver/adc.h> and the function adc_power_acquire(); in the Arduino program
The battery life of the controller is affected by various factors such as battery capacity, operating status, and load, so there is no fixed value. Reducing the load and adopting a sleep strategy can effectively increase the battery life.
Support multiple stacks, the total capacity of the batteries in parallel increases, and the voltage remains unchanged. However, since the discharge of each battery is not balanced during use, there is a voltage difference between the batteries, which may cause the battery to charge backwards. .(will lose part of the battery capacity)
ESP32 module currently does not support WiFi in 5G band, only 2.4G.
Confirm whether the TX/RX pin on the TTL side of the pin is correct, try to add two 120Ω terminal resistors at the beginning and end of the device line to reduce signal reflection interference

Rotate the lens to adjust the focal length within a certain range
Use esptool to read the flash content of esp32 and export the bin file. Refer to the detailed operation
Restart the Arduino IDE, the computer uses the mobile AP mobile network to download.
Refer to the Github link below, use arduino-esp32fs-plugin for file upload
Check if the COM of the corresponding device is selected and if the M5Burner is the latest version
UIFlow users can switch the Label font to Unicode, Arduino users can use the Chinese font library provided in the M5GFX driver library
Confirm whether the SD card format is FAT32, and no partitions exist.
You can refer to the following link for other ESP32 users to share the case program
STAMP C3U enters program download mode operation: 1. Long press the center button (G9) of STAMP C3U when the power is off. 2. Connect to the computer, after the port is successfully identified, program burning.
By default, USB CDC is not enabled, the serial port output started by C3U will be output through the default pins (G20, G21) of UART0. If you want to output through USB, please use the IDE to output Its USB CDC option is enabled. (Arduino users can enable it through Tools->USB CDC on Boot-Enabled. For IDF users, please refer to the ESP IDF official documentation.)
Refer to the UIFlow documentation of the corresponding device to check whether the device has entered the USB programming mode.
Describe the problems encountered in detail. Screenshots of the programs involved or files can be added as attachments and sent to M5Stack's official after-sales email
