Control the QM12038 by NRF9160

[chapman]

Hi 

I want to know if there is any source code of thingy91. 

Because I want to follow thingy91 for making a product with the use of the same antenna, and I want to know how to control the rf analog switch for the antenna.

It seems it will require to control QM12038. I want to know how to modify the code to search at different band.

Can you tell me which part of the code is referring to this?

Thank you.

Hi,

The Thingy:91 firmware (Asset tracker) can be found here: https://github.com/NordicPlayground/fw-nrfconnect-nrf/tree/master/applications/asset_tracker

You need to build the project using the right board: nrf9160_pca20035ns for it to work with the Thingy:91.

The QM12038 switches are control using the MAGPIO pins on the nRF160. These need to be configured via AT command %XMAGPIO.

Take also a look at the hardware files for the Thingy:91 and this application note published by Fractus for more information about the design for multiple matching networks.

Best regards,

Marjeris
