Hi,
I'm a beginner trying to understand BLE extended advertising. I have modified the peripheral/ble_app_beacon example to broadcast extended advertising packets with PHY=Coded. I'm receiving the packets using the pc-ble-driver with a modified "heart_rate_collector" example. I'm using two nrf52840 dongles.
I'm currently able to read the entire data that I transmit on the advertising packet, and some other bytes like the source address using the following code:
static void on_adv_report(const ble_gap_evt_t *const p_ble_gap_evt)
{
uint32_t err_code;
uint8_t str[STRING_BUFFER_SIZE] = {0};
// Log the Bluetooth device address of advertisement packet received.
ble_address_to_string_convert(p_ble_gap_evt->params.adv_report.peer_addr, str);
printf("Received advertisement report with device address: 0x%s\n", str);
printf("Extended?: %d, channel: %d, data len:: %d\n",
p_ble_gap_evt->params.adv_report.type.extended_pdu,
p_ble_gap_evt->params.adv_report.ch_index, p_ble_gap_evt->params.adv_report.data.len);
//Printar data:
int i;
for (i = 0; i < p_ble_gap_evt->params.adv_report.data.len; i++)
{
printf("%02X", p_ble_gap_evt->params.adv_report.data.p_data[i]);
}
printf("\n");
fflush(stdout);
}
..but I would like to see all the raw packet that I'm receiving (both primary and secondary extended advertising packet). I think the raw packet should begin with a 0x3C (preamble) byte since I'm transmitting and receiving with coded phy. Is there any form to visualize all the bytes (including the preamble byte)?
Thanks in advance.
