Hardware Documentation?

[awneil]

Where is the hardware documentation?

ie, the schematics, pinouts, jumper descriptions, etc?

[awneil]

Well, user 'Clive One' has posted a pinout list in the ST Community:

https://community.st.com/thread/43664-i-nucleo-lrwan1#comment-172409

But come on, guys - your customers should not have to be reverse-engineering your products!!

[GrumpyOldPizza]

I had e-mailed USI a while ago and gotten no reply. It would be helpful to get the schematics for the WM-SG-SM-42 Shield as an experimentation platform ...

[awneil]

Yes, I have also emailed them - and had no reply.

Designing-in this module looks like a high-risk venture if this is the level of support they provide ...

:(

[GrumpyOldPizza]

I would not go that far yet. Perhaps if I'd buy 5000 from them I'd get attention. But first off I need to evaluate this thing, and they put out I-NUCLEO-LRWAN1 (or WM-SG-SM-42_Shield_V1.0 as the label says). I cannot use it properly, because I don't know how to disable the extra stuff on the PCB to measure power. I cannot check into ANYTHING else but SWD/LPUART, because I don't know what is connected to what ...

I do kind of like the formfactor, and with a different pinmapping (not LPUART) it might be interesting as slave to a STM32L4xx (assuming it's cheaper than the competing module).

Its schematic has been uploaded at Feb 1, please chech it.

[USI-ShellyWu]

Please also notice that the latest FW was uploaded. https://github.com/USILoRaModule/USI_I-NUCLEO-LRWAN1/blob/master/preloaded_firmware/wm-sg-sm-42_firmware_v3.3.hex

[awneil]

Great - a schematic at last!

Thanks.

But why did it have to take over 3 months ??

[rogerdahl]

Wish it had been only 3 months! It's been 7 months since I picked up my boards at Mouser.

I have been doing reverse engineering and have completed a custom firmware that sends out LoRa packets with values from the sensors. I plan on pushing it to GitHub after some cleanup.

Thanks, though! It's great to have the schematics at last -- better late than never :)

[rogerdahl]

I also emailed customer support at USI a couple of times asking for this. Never got any reply. That's no way for a company to do business.

[USI-ShellyWu]

So sorry for missing your requests for long time.

[on4eco]

Indeed a board that give me headache revers what??

[et1975]

Are the sources for the shield firmware available somewhere?

[USI-ShellyWu]

Please check the tree: USI_I-NUCLEO-LRWAN1 / preloaded_firmware / v3.3 is the latest

[awneil]

The request was for sources - there are only Hex files there.

:(

https://github.com/USILoRaModule/USI_I-NUCLEO-LRWAN1/tree/master/preloaded_firmware

[USI-ShellyWu]

the source is downloaded from ST website: http://www.st.com/content/st_com/en/products/evaluation-tools/product-evaluation-tools/mcu-eval-tools/stm32-mcu-eval-tools/stm32-3rd-party-evaluation-tools/i-nucleo-lrwan1.html

[awneil]

You mean: http://www.st.com/content/st_com/en/products/evaluation-tools/product-evaluation-tools/mcu-eval-tools/stm32-mcu-eval-tools/stm32-3rd-party-evaluation-tools/i-nucleo-lrwan1.html ?

Does that actually include the source to run within your module?

EDIT

Sorry, link should be: http://www.st.com/content/st_com/en/products/embedded-software/mcus-embedded-software/stm32-embedded-software/stm32cube-expansion-packages/i-cube-lrwan.html - ie, the I-CUBE-LRWAN LoRaWAN software expansion for STM32Cube (UM2073)

[USI-ShellyWu]

I think it must be built not run within SM42 directly. FW in github can be programmed and run within SM42 that can support AT commands.

[ale16384]

Hi,

Can you please post hw_conf.h file for AT_Slave example too? From the patch it is not clear to me which file it is necessary to include. A draft schematic of the module would be helpful as well..

[bekir35]

I have hardware WM-SG-SM-42_SHIELD_V1.0

How can I install the latest version of the usi module on it?

Actually, we controlled from an external host such as NUCLEO-L073 boards.Downloaded the software STM32CubeExpansion_LRWAN_V1.3.1. At_master code works fine but End_Node code is not working.How can we solve this problem?

[aithalks]

Very Poor documentation by ST Micro electronics.

[awneil]

@aithalks : it's not ST's product and, therefore, not ST's documentation; USI is a 3rd-party "partner" - so the documentation (or lack thereof) is down to USI.

[aithalks]

@awneil, But ST's P-NUCLEO-LRWAN2 is bundled with this product. Is it not your responsibility to make sure that correct document is made available to the user / developer. I have not found the hardware document for I-Nucleo-LRWAN1. github has schematic for only WM-SG-SM-42 module.

[awneil]

@aithalks I am just a user like you - I have no affiliation with either ST or USI.

But this is USI's GitHub - if you want to raise issues with ST, then you need to do that via ST's own channels.

FWIW, I do agree that the status of "Partner" should imply a greater support / involvement from ST.

[aithalks]

@awneil : My apologies to you. After reading your first comment, I got the impression that you are from ST. Still the bottom line is, showing fingers to other partner, when it comes to solving the problems (Between ST and USI)
