Are these appropriate LoRaWAN learning tools

I own a NUCLEO-L053R8.

Is it appropriate to get a I-NUCLEO-LRWAN1, plug it into the NUCLEO  and use the I-CUBE-LRWAN (STM32CubeExpansion_LRWAN_V1.1.2) to start learning LoRaWAN?

Is the NUCLEO-L053R8 with the I-NUCLEO-LRWAN1 plugged in essentially the same as a B-L072Z-LRWAN1???

Why risk it?

Why not just get a B-L072Z-LRWAN1 Discovery board, or a P-Nucleo-LRWAN1 kit?

That way, you know you have a complete kit, and you get ready-to-run examples specifically made for it - no messing about with trying to ensure that everything is compatible.

Simples!

Ah - no, it isn't.

The 

I-NUCLEO-LRWAN1 has a USI module and is really just intended as a dumb modem - using AT commands:

The USI module has a 

Semtech SX127

2

radio.

As noted elsewhere, the USI documentation is, well, 'lacking' ...

>:(

The Discovery board uses a muRata module with SX127

6

, and is well documented.

Note that the 

P-Nucleo-LRWAN1 kit also use the 

SX127

2

.

The USI part can be reprogrammed, but it's a non-ideal development platform. The LRWAN that ST supplies is relatively portable across boards and platforms.

Indeed - but the OP specifically asked about this as a starting point.

Of course, stuff can be ported & adapted - but I really don't think that's great as

a

starting

point.

The P-NUCLEO-LRWAN1 package includes both shield and Nucleo board ($70), it is the most expensive path. You can buy the shield and board separately more cheaply. The SX1272 shield can be bought more cheaply $25, and a Nucleo for $10, but you already have that.

The B-L072Z-LRWAN1 is a different beast, and perhaps the optimum development/learning platform. The L0 has 192KB of FLASH, and the module uses the SX1276 radio.
