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.

Hi

Gottardello.Deni

‌,

• I advise you to have look at

  embedded software expansion.It consists of a set of libraries and application examples for STM32L0, STM32L1 and STM32L4 Series microcontrollers acting as end-devices.For further details, please refer to

may also help you.

• Combined with the software expansion package I-CUBE-LRWAN, the

  below are the quickest way to build LoRaWAN end-node devices:- Low-power wireless Nucleo pack (P-NUCLEO-LRWAN1) - STM32L0 Discovery kit LoRa, low-power wireless(B-L072Z-LRWAN1)- USI STM32 Nucleo expansion board for LoRa (I-NUCLEO-LRWAN1)

Khouloud.

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.

Who sells the

B-L072Z-LRWAN1

, both Digikey and Mouser have zero stock.

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

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
