THingy91: Any sample applications for nRF91 FW showing interface to nRF52?

Dave_couling

I've seen the Connectivity Bridge Application in the ncs,  however I can't find any sample application for the nRF91 side showing how it can send/receive data and events from the nRF52?  Is this yet to be built out?  What is the default FW inside the nRF52 on the Thingy91?

    The connectivity bridge will simply forward data to/from the nRF9160 SiP to/from the USB (computer). If you would like the Thingy:91 to have this capability (forward data) and also the possibility to send events from the nRF52 you have to modify the connectivity_bridge sample (or the usb_uart_bridge sample), you have to modify the sample. Please tell me if this is the case, and I can tell you how to go aboutthis. If not, you could program the lpuart sample on both the nRF9160 and the nRF52840 to communicate over UART.

    What is the default FW inside the nRF52 on the Thingy91?

     I've asked internally about this. I'll get back to you soon.

    If you have an old version of the Thingy:91 the usb_uart_bridge should be on the nRF52840. On the current/newest versions of the Thingy:91, the connectivity_bridge should be on the nRF52840.

    There has been som issues with the connectivity_bridge lately and it may be smart to upgrade to the latest sample. Either NCS v1.3.1 or v1.4.0

    Hi Simon,

    For now, being able to forward events to the nRF52 is ideal.  However in our first release we'll be disabling Logging to optimize power consumption.  So I need to make sure events are still received by the nRF52 when Logging is disabled.  Is this possible?

    I think the lpuart sample is a good option for you, it has disabled logging by default.

    Best regards,

    Simon
