Hi. I have to study the lora world with a stm32 microcontroller.

For me it is the first approach. Can someone suggest me witch stm32 demo board is the most easy to use in order to learn how lora works?

Can someone suggest me a tutorial?

I need to use lora as sensoristic application.

    I'd recommend the 

    B-L072Z-LRWAN1, it is a DISCO board which includes and ST-LINK debugger and the LoRa via a Murata part including an STM32L0 device and the SX1276 radio.

    The USI module is a closed source solution, and the AT modem firmware lacks refinement, the L0 part has significantly less memory, and it uses the older SX1272 radio. I would avoid.

    The NUCLEO and SX127x radio pairings work well.

    The 

    I-CUBE-LRWAN works relatively seamlessly across a number of board combinations, although the code has some significant deficiencies.

    I'm using LoRa as a point-to-point radio link.

    They had stock, and sold it. You'll have to back order and wait for deliveries.

    If August isn't appealing, then consider your other options

    Bunch of stock of the P-NUCLEO-LRWAN1 combo board. Qty 222 as I type

    Hello,

    I would like to recommend to you one of our on-line courses dedicated to LoRa.

    It is a recording of our LoRa workshop session from last year.

    Session is free and it requires a free registration.

    More information and access link you can find
