Distance measurement with nRF9160DK/nRF7002DK

ptejasv

Hello, and thanks for your help.

I'm working on a project that uses MCPD distance measurement from the nRF Connect distance measurement library. I've been using multiple nRF52840DKs with the Distance Measurement with Bluetooth LE Discovery sample (using the nRF Connect SDK v2.2.99), but my project requires that devices performing the MCPD measurement be able to connect to a database over TCP/IP, so it would need WiFi or LTE coexistence with BLE and MCPD.

I saw that the nRF9160DK has an nRF52840 board controller built in. Will this mean the nRF9160DK can be used for distance measurement with MCPD? If so, can the sample program be run as-is for the nRF52840DK? I have the same question for the nRF7002DK, which I saw has an nRF5340 chip on board.

If neither of these boards support distance measurement via MCPD, is there a way to connect an nRF9160/nRF7002 to an nRF52840 perhaps via the SPI interface to use it as an external LTE/WiFi support?

Thank you.

    Hello Paramita,

    Will this mean the nRF9160DK can be used for distance measurement with MCPD?

    Yes, if you flash the nRF52840 SoC on the 91Dk that should work. You can do this by turning SW10 to "nRF52" on the DK.

    If so, can the sample program be run as-is for the nRF52840DK?

    This I am not sure if I understand. Are you wondering if the other code running on the nRF52840DK can be run as-is in order to communicate with the nRF52840 on the nRF9160DK?

    I have the same question for the nRF7002DK, which I saw has an nRF5340 chip on board.

    Yes. nRF53832, nRF52833, nRF52840 and nRF5340 are supported (the others aren't due to memory requirements).

    If neither of these boards support distance measurement via MCPD, is there a way to connect an nRF9160/nRF7002 to an nRF52840 perhaps via the SPI interface to use it as an external LTE/WiFi support?

    Yes, connecting two SoCs would otherwise be the way to go. This is also the reason why there is an nRF52840 on the nRF9160DK - just to add Bluetooth capabilities to the DK.

    Thank you, this answers most of my doubts.

    Yes, my question was if the hardware settings configured for the distance measurement sample would affect how it works with the nRF52840 on the nRF9160DK.

    Yeah, I do not believe that should be a problem. It will work the same way no matter the DK it is on.
