This TinyGo application was initialy written for testing sx126x and sx127x drivers interoperability.

AT-style commands sent on usart let you change Lora module modulation:

• Frequency (AT+FREQ)
• Spread Factor
• Coding Rate (AT+CR )
• Header type (implicit/explicit)
• CRC (on/off)

Then you can send and receive Lora message with the defined configuration

How to use

Just select your device (with -target) and the radio driver (with -tags):

Then you can flash it:

# LoraE5 with sx126x (STM32WL's internal Lorawan radio)
tinygo flash -target=lorae5 -tags sx126x

# Bluepill with external sx127x module connected through SPI
tinygo flash -target=bluepill-clone -tags sx127x

Supported Lora modules :

• sx126x (Only tested on STM32WL5x SoCs that embedded sx126x)
• sx127x (Present on various Lorawan modules : eg: RFM95)
