I bought p-nucleo-lrwan2 package at two weeks ago.

so I have searched p-nucleo-lrwan2 reference source.

I get p-nucleo-lrwan1 endless board source, but I haven't find p-nucleo-lrwan2 gateway source.

please I hope to get p-nucleo-lrwan2 gateway source.

have a good day

It seems the software is not open...

I have also bought a new package of this:

P-NUCLEO-LRWAN2

STM32 Nucleo pack LoRa™ HF band sensor and gateway

The node does not respond to AT command. The gateway do.

ST's quality control is very bad! They do not verify it before they ship this product.

ST's support is also horrible. They tell you to read large amount of books and manuals.

Yeah, that's how a lot of engineering is done, beats constructing planes from straw..

The USI parts should be pre-programmed, the NUCLEO side needs to port-forward a UART connection over the ST-LINK VCP if you want to use AT commands on the PC terminal, or host the AT command interaction locally.

Hello Clive,

The point is, the out-of-box demo does not work as described as in the package's manual:

The sensor node board with the USI I-NUCLEO-LRWAN1 shield does not respond to AT command through a Tera terminal.

Many customers experience this and have not solved this problem for a long time.

Hi @Timmy​ ,

I am also facing the same problem.

Please let me know if you have found the solution.

Thanks and regards,

Hello,

ST support replied me that the base Nucleo Board is not compatible with the USI I-NUCLEO-LRWAN1 shield!!!

I have requested a picture showing the correct connections between base board and shield. I will upload here after they will have replied me.

I would like the source or at least update the firmware in the gateway. The firmware is using an old version of the Semtech UDP Packet Forwarder protocol. The protocol version in the UDP packets is set to one. This is causing integration issues with other stacks. The protocol version was changed four years ago.

I also had difficulties sending AT commands to the I-NUCLEO-LRWAN1 shield. The documentation is not clear on how to do it. First you have to remove the shield from the NUCLEO-L073RZ main board. The main board is controlling the expansion board through the same serial interface for the AT command console. You have to use a USB to 3.3V TTL serial. You can regulate the 5V VCC to 3.3v or use another 3.3V source. The pinouts are below:

  • CN8 pin 1 TX
  • CN8 pin 2 RX
  • CN6 pin 4 +3V3
  • CN6 pin 6. GND

The pinout is also in Figure 19 in document UM2587. Section 4.2 tells you how to connect to the expansion but has useful details like the main board USB cannot be used for the AT commands and the expansion board serial lines are in use back in a footnote in section 1.1.1. I spent many hours banging my head against the wall before I figured out how to program the I-NUCLEO-LRWAN1 and that the bug was the root cause of my connection failures.

Dear Ducphuc,

Thank You! You have provided much more information than ST's employees! They simply answer me "read from page *** to ***." Full Stop! I guess ST is now a fully China-rised company using China's unique AI technical support! ;)

First of all, I will try to contact the vendor for an updated firmware of RisingHF ARDUINO expansion board (LRWAN_GS_HF1)

Secondly, I also provide this alternative implementation of the node part. It is a STM32duino library. However, I am not successful with their method. Perhaps, my node's firmware is not the same as these users':

Ducphic,

I can only find this gateway's information. I guess they have removed information of LRWAN_GS_HF1 expansion board
