Nordic provides a lot of ready to use tools which are quite useful. They also have a lot of useful code and documentation. They base their ecosystem on Zephyr, but it's still useful. BLE sniffer can be found here https://www.nordicsemi.com/Products/Development-tools/nrf-sniffer-for-bluetooth-le/download The dongle comes with factory-programmed Nordic's bootloader so it was possible to flash fw using this method (and flash sniffer fw). But Nordic messed up their tools a lot, so honestly I have no idea with which bootloader version they ship the dongle now (and which tools are compatible) pt., 2 lut 2024 o 17:37 Sebastien Lorquet <sebast...@lorquet.fr> napisał(a): > Hi, > > Thank you very much for your advice. > > I can probably get a -DK.
