Zephyr Connectivity: BLE

Implement robust, low-power Bluetooth Low Energy applications using Zephyr's industry-standard BLE stack.

Core Workflows

1. BLE Fundamentals

Set up advertising, define GATT services, and manage connections.

• Reference: ble_fundamentals.md
• Key Tools: BT_GATT_SERVICE_DEFINE, bt_le_adv_start, BT_CONN_CB_DEFINE.

2. Send-When-Idle Pattern

Optimize radio usage by bundling data and transmitting only during idle periods.

• Reference: send_when_idle.md
• Key Tools: k_work_delayable, Workqueues, SMF integration.
