<alp/ble.h> — Bluetooth Low Energy 5.4

BLE peripheral and central support.

#include <alp/ble.h>

Peripheral (advertising + GATT server)​

alp_ble_t *ble = alp_ble_open(&(alp_ble_config_t){
    .role        = ALP_BLE_ROLE_PERIPHERAL,
    .device_name = "ALP-Sensor-01",
});

alp_ble_advertise(ble, &(alp_ble_adv_config_t){
    .interval_ms = 100,
    .connectable = true,
});

// GATT service registration via alp_ble_gatt_register_service(...)

Central (scan + connect)​

alp_ble_t *ble = alp_ble_open(&(alp_ble_config_t){
    .role = ALP_BLE_ROLE_CENTRAL,
});

void on_device(const alp_ble_scan_result_t *r, void *user) { /* ... */ }
alp_ble_scan_start(ble, on_device, NULL);

Backend​

  • AEN family — BLE rides the same TI CC3501E coprocessor as Wi-Fi. See the CC3501E section.
  • V2N family — BLE rides the Murata LBEE5HY2FY-922 combo module (UART HCI).

The application API is identical.
