hello Dialog,

hello Dialog,

thank you for your Answer,

when i´m debugging the code I have seen manufaturer specific data in advertsising data of ble in ble scanner app.

The Link that you sharing me talk about the Adversting Data and i want to write my custoom Data in the manufaturer specific data.

the Data format look like this:

Result = 1604937913613 ScanResult{device=80:EA:CA:80:00:01,
scanRecord=ScanRecord [mAdvertiseFlags=6,
mServiceUuids = [00002 ea7 - 0000 - 1000 - 8000 - 00805f9b34fb,
0000180f-0000-1000-8000-00805f9b34fb,
0000c8c5-0000-1000-8000-00805f9b34fb,
0000180d-0000-1000-8000-00805f9b34fb,
0000fef5-0000-1000-8000-00805f9b34fb],
mServiceSolicitationUuids=[],
mManufacturerSpecificData={210=[-128, 0, 1]},
mServiceData={},
mTxPowerLevel=-2147483648,
mDeviceName=Dialog WRBL],
rssi=-62,
timestampNanos=18950393039360,
eventType=27,
primaryPhy=1,
secondaryPhy=0,
advertisingSid=255,
txPower=127,
periodicAdvertisingInterval=0}

thank you

Hi Lionel03,

Hi Lionel03,

The manufacturer specific data is a part of the advertising string, so the suggested tutorial should be taken as reference. In step #1 there is an example demonstrating how to set the adv data.

The GAP Advertising Data Types, as defined by Bluetooth Core specification can be found in gap_data_type_t structure in ble_gap.h.

The GAP_DATA_TYPE_MANUFACTURER_SPEC should be used for the Manufacturer Specific Data. Again you should follow the concept from the GAP_DATA_TYPE_LOCAL_NAME. Additionally the ble_gap_adv_data_set() should be used in order to set either the adv or scan response data.

Please see an example below :

static const uint8_t adv_data[] = { 0x04, GAP_DATA_TYPE_LOCAL_NAME , 'A','B', 'C', 0x05, GAP_DATA_TYPE_MANUFACTURER_SPEC, 0x00, 0x01,0x02, 0x03, }; static const uint8_t scan_resp[] = { 0x11, GAP_DATA_TYPE_UUID128_LIST, 0x11, 0x22, 0x33, 0x44, 0x55, 0x66, 0xAA, 0xBB, 0xCC, 0xDD, 0xEE, 0x00, 0x00, 0x00, 0x00, 0xAA, }; /* Set advertising data */ ble_gap_adv_data_set(sizeof(adv_data), adv_data, sizeof(scan_resp), scan_resp);

Thanks, PM_Dialog
