Record and Download

Device-local recording runs on the M1 and survives a host disconnect. Stop it before downloading the MCAP.

#include <chrono>
#include <thread>
#include <ef/Device.hpp>

int main() {
    ef::Device device;
    if (device.open() != ef::ERROR_CODE::SUCCESS) {
        return 1;
    }

    ef::RecordingParameters recording;
    recording.target = ef::RECORDING_TARGET::DEVICE_LOCAL;
    recording.name = "wired_session";

    if (device.enable_recording(recording) !=
        ef::ERROR_CODE::SUCCESS) {
        return 1;
    }

    std::this_thread::sleep_for(std::chrono::seconds(5));
    device.disable_recording();

    ef::ERROR_CODE status =
        device.download_recording("wired_session", "wired_session.mcap");
    device.close();
    return status == ef::ERROR_CODE::SUCCESS ? 0 : 1;
}

BLE carries recording control and the file download; WiFi is not required.

    init.input_type = ef::INPUT_TYPE::STREAM;
    init.ble_address = "AA:BB:CC:DD:EE:FF";
    init.ble_password = "123456";

    ef::Device device;
    if (device.open(init) != ef::ERROR_CODE::SUCCESS) {
        return 1;
    }

    ef::RecordingParameters recording;
    recording.target = ef::RECORDING_TARGET::DEVICE_LOCAL;
    recording.name = "wireless_session";

    if (device.enable_recording(recording) !=
        ef::ERROR_CODE::SUCCESS) {
        return 1;
    }

    std::this_thread::sleep_for(std::chrono::seconds(5));
    device.disable_recording();

    ef::ERROR_CODE status = device.download_recording(
        "wireless_session", "wireless_session.mcap");
    device.close();
    return status == ef::ERROR_CODE::SUCCESS ? 0 : 1;
