FRDM RW612 - zephyr rtosでbluetoothを使用してみる。
- はじめに
NXPの無線通信対応マイコン評価ボード「[FRDM-RW612] (https://www.nxp.jp/design/design-center/development-boards-and-designs/FRDM-RW612)
および、zephyrのサンプルアプリケーションプログラム(samples/bluetoot)および開発用のツール（tests/bluetooth/shell）を使用して、bluetoothの動作を確認してみた際の記録メモです。
- ビルド前の事前対応
$ west blobs fetch hal_nxp
- ビルド
$ west build -b frdm_rw612 samples/bluetooth/ビルド対象のサンプル/ -p always
- 基板への書き込み
$ sudo env "PATH=/usr/local/LinkServer_26.3.123:$PATH" $(which west) flash -r linkserver
- 上記ビルド前の事前対応～基板への書き込みについては、下記を参照。

bluetoothのサンプルアプリケーション、開発ツールの実行例
- サンプルアプリケーションのディレクトリ samples/bluetooth
- サンプルアプリケーションとは別に、開発用のツールとしてtests/bluetooth/shellが利用できた。
- サンプルアプリケーションおよび開発用の実行例を以下に示す。（サンプルアプリケーションは複数あるため、一部をピックアップしている。）
