Problem with OM2385/SF001 Development Kit

igormp — Mon, 18 Sep 2017 17:50:25 GMT

I'm currently facing a weird error while trying to use the DemoConsole example listed in the user guide for the OM2385/SF001 kit (which contains a OL2385 SIGFOX module and a KL43Z development board). The board itself seems to be working fine, since I'm able to run other available examples, but the example meant to make use of the Sigfox module throws the error shown in the picture bellow instead of a menu with options to chose from.

And here is an image of the menu that should be displayed, according to the manual:

Any help would be appreciated.

Hi Igor,

It seems like you are getting or having some connections problems with the OL2385. I have a similar issue when I disconnect the OL2385 from the KL43

Could you please check the voltage of the next pins?

Let me know your findings

Regards,

Mario

Hi Mario,
I'm having the same problem that Igor mentioned above, including i has downloaded the embedded software available on the NXP website (here).
Here is the voltage of the requested ports of the board:

EDIT:

3v3 -> 3.06V
ACK -> 3V
CS -> 3V
MOSI -> 3V
MISO ->3V
SCK -> 3V

Hi Mario,

All of the pins are runing at around 3v~3.1v.
I believe that's a software issue, since I was able to connect to the network after slightly changing the example's source code to ignore the error message.

Any further help would be appreciated.

Hi Jonathan/ Igor,

Just to confirm,

Did you register your device in https://backend.SIGFOX.com/activate ?

7.1.1 Registering SIGFOX device on network

Hi Mario,

I did register my device, and followed the guide to heart, but it still fails in the 7th step of 5.4.1.3 Setting up terminal program, as shown in my previous pictures, even after updating the bootloader and binary file.

Hi Igor,

Could you please try with the Console Control example?

Please let me know your findings.

Best Regards,

Mario

Hi Mario,

I got it to work (along with all the other demo codes) by ignoring some weird error code the device was throwing on the SPI bus (error code 0xFF, which is not listed in the error code table).

By simply checking if the error matched 0xFF and setting it to 0x0 I managed to compile & run the demos :smileyhappy:

BR,
Igor
