EWIZZ Please advise on how to flash the DECT softdevice to the Feather?
You mean the modem firmware?
1. Install the Rust toolchain
Install Rust using rustup.
On macOS and Linux:
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
On Windows download and run the installer from rustup.rs, then open a new PowerShell or Command Prompt window.
After installation, confirm the toolchain is available:
rustc --version
cargo --version
Install the updater:
cargo install --git https://github.com/circuitdojo/modem_updater.git
Run the updater:
To program and verify the modem firmware, run:
updater program <path_to_firmware_zip>
Here’s the usage output with example:
Modem Updater Usage:
updater <operation> <firmware_path>
Operations:
verify - Verify firmware at the specified path
program - Program and verify firmware at the specified path
Example:
updater program _bin/mfw_nrf91x1_2.0.2.zip
Binaries are also pre-built by CI if you’d like to download/use that way as well:
