Cannot find LoRa PingPong example. B-L072Z-LRWAN1 (or other L0 resources)

[Mo3biu5]

Hello everyone.

4 years ago i began developing a project from this board B-L072Z-LRWAN1 using a LoRa "PingPong" example.

Now i want to re-start this project on Nucleo-STM32WL55, but there is not a "LoRa PingPong" example, only a SubGhz PingPong (alas, i need the lora middleware for authenticating ingoing and outgoing packets).

Fact is: I want to take some code from the old Ping Pong example on B-L072Z-LRWAN1 , but i cannot find it anymore!

I tried to:

• Use current CubeMX with NUCLEO-L073RZ (or similar L0 boards). See picture attached.
• Manually download L0 package v. 1.12.1, but did not find the example among files. (picture attached)
• Use a old version of cubeMx (6.1.0), still no lora ping pong example.

Has it been removed? Anyone has a clue? I would really love to have the source code again

Thank you very much if you have any hint!

Not sure the example got made into CubeMX/IDE .IOC files

STM32CubeExpansion_LRWAN_V2.1.0\Projects\B-L072Z-LRWAN1\Applications\SubGHz_Phy\SubGHz_Phy_PingPong

Earlier versions are still serviceable, I'm using Keil

STM32CubeExpansion_LRWAN_V1.3.1\Projects\B-L072Z-LRWAN1\Applications\LoRa\PingPong

Hello @Mo3biu5​ ,

We never implemented the Ping-Pong example with the LoRaWAN middleware that imply to have a network, but in this example you just have a peer to peer connexion.

Also even with a newer version of CubeMx you can still find old examples, the version of this tools don't impact the example version's you can find in it.

Concerning the example, you won't find them if you look for Nucleo-L073RZ, we release an extension package targeting STM32L0 Series, STM32L1 Series, and STM32L4 Series.

This package includes an application running on NUCLEO-L053R8, NUCLEOL073RZ, NUCLEO-L152RE, NUCLEO-L476RG, and B-L072Z-LRWAN1 embedding the CMWX1ZZABZ-091 LoRa® module (Murata).

So you can find example for your board from this package.

Regards

Louis

Thanks a lot for your responses!

Looks like I was looking something never existed in the first place. I thought there were a Ping Pong example which utilized the LoRa middleware (with authenticated messages), instead of just being subghz packets.

I am taking inspiration from the material you pointed me, Louis.

Thanks yo everyone

Best regards
