Communication between nrf52840 and nrf9160 on thingy 91

[Hamada888]

Hei

I am trying to make SPI or UART communication between nrf9160 and nrf52840 on thingy 91....... i need to send data from nrf52840 to nrf9160(i will use and print the data)
what is the best way to do it? I tried connectivity bridge, but with no hope......

Another small question....i cannot get any thing out on putty when i write printk("hello world"); in the main function in connectivity bridge code ...how to fix it?

Hello Mohammad,

configuring the LPUART in the asset tracker application is unfortunately not that straight forward. But I’m not sure if you need that, actually.

UART0 and 1 are already pre-configured in the asset tracker, so you could use them as they are (and of course modify them via an overlay-file). You just replace the argument in the get binding function, eg.:

uart0_dev = device_get_binding("UART_0");

If you want to check the labels you can have a look at zephyr.dts in ../<your_build_folder>/zephyr.

Let me know if you have any more questions!

Regards,

Markus
