Searching for a sample

Youssef Elbattah

Hello,

I came across a Nordic Q&A discussing a sample called hci_uart_with_usb_uart_bridge in this post. I have searched in the v1.0.1 tag but couldn't find the mentioned sample.

Could you please guide me on how to locate this sample?

Best regards,

Youssef

    Hello Youssef, 

    What version of the nRF Connect SDK are you working on? You are referring to a post from 2019, where they present a very old version of our SDK: v1.0.1. The current version is v2.6.1, while v2.7.0 is right around the corner (after summer). 

    Are you working on the nRF9160 DK or the Thingy:91?

    What is the intension? Have you looked at the latest version of our Cellular: LTE Sensor Gateway sample? Note that this sample is for the nRF9160DK.

    Kind regards,
    Øyvind

    Hello Øyvind,

    I am currently working with version 2.5.0 on the Thingy:91 and need a sample that merges the applications of connectivity_bridge and hci_lpuart.

    My goal is to establish communication between the nRF52 and nRF9160 on the Thingy:91. I have managed to achieve communication using UART1, but I am facing the following issues:

    1. When using UART1 in async mode, the Rx gets disabled automatically after receiving a packet from one of the devices.
    2. I want the Thingy:91 to be visible to a terminal, allowing me to send packets to the nRF9160. I believe the connectivity bridge application can facilitate this, but I need a sample that integrates both hci_lpuart and connectivity_bridge.

    Could you please provide guidance or a sample project that achieves this integration?

    Best Regards,

    Youssef

    Update !

    About the first issue, i have already found the solution, but for the second issue i want to add some explanation.

    I want to keep the connectivity bridge because i need to download some PSK keys via USB of the thingy91, while still doing the bridge between the nrf52840 and nRF91 (Cellular to BLE bridge). The processing and handling of BLE must be kept on the nrf52840 side since i do not have a lot of flash remaining on the nrf9160 side.

    Best Regards,

    Youssef

    Hello Youssef, 

    As stated, the official answer to this is that the Thingy:91 is not supported in the Sensor Gateway sample. The Thingy:91 relies on the Connectivity Bridge to enable USB support, and to communicate between the nRF9160 and the nRF52840. The nRF52840 on the Thingy:91 is primarily used as a USB to UART bridge, so it is possible to get logs from the nRF9160, and to do DFU over USB (See the Thingy:91 Getting started guide).

    We have reported the wish for Thingy:91 support, however, this is not prioritized as the Thingy:91 designed for showcasing the nRF9160. 

    Kind regards,

    Øyvind
