Connecting nRF9610 and nRF52xxxx

[capodic]

Hi all,

I'm evaluating design for a bluetooth + GPS + NB-IoT ultra-low power device

I see the only possibility to get a such module is to design it (I didn't found anything on the market that is real low power...)

I was thinking to connect nRF9160 and nRF52xxxx but I never used Nordic chip before. Is it a good idea ? Alternative I thought is ESP32 + nRF9160...

Which is the best way to interconnect nRF9610 and nRF52xxx ? SPI ?

Don't uBlox have something?

There is no such thing as "best" - it all depends on your specific requirements & constraints.

But the nRF52 certainly support all the usual suspects; UART, SPI, I2C - or roll your own ...

Very good idea :)

We have an example/sample called LTE Sensor Gateway in NCS for this use-case. See this and this link.

It uses UART to connect the nRF9160 and the nRF52840 together. The Bluetooth Controller is running on the nRF52840, and the Bluetooth Host is running on the nRF9160. You can use the nRF9160-DK to test the sample.

Hi Sigurd, thanks for your suggestion, I'll take a look
