Affected products: PSoC™ 4 and PSoC™ 6 MCUs with AIROC™ Bluetooth® LE.
In Bluetooth® LE GAP Peripheral role, when a device is advertising, you can change the advertisement and scan response data by using APIs as follows:
For PSoC™ 4 CY8C4x47xx-BLxxxx MCU with AIROC™ Bluetooth® LE:
The CyBle_GapUpdateAdvData API function is used for setting the advertisement and scan response data while advertising is ongoing. This API function must be called when CyBle_GetBleSsState() returns the CYBLE_BLESS_STATE_EVENT_CLOSE state. See the following sample code segment:
if(CyBle_GetBleSsState() == CYBLE_BLESS_STATE_EVENT_CLOSE)
{
/* Update the ADV and Scan Response data */
cyBle_discoveryModeInfo.advData->advData[5]=0x06;
cyBle_discoveryModeInfo.scanRspData->scanRspData[5]=0x05;
/* Update the ADV and Scan Response data */
CyBle_GapUpdateAdvData(cyBle_discoveryModeInfo.advData,
cyBle_discoveryModeInfo.scanRspData);
}
For PSoC™ 6 CY8C63x7 MCU with AIROC™ Bluetooth® LE:
The Cy_BLE_GAPP_UpdateAdvScanData API function is used for setting the advertisement and scan response data while advertising is ongoing. On completion of this operation, the GAP Peripheral application receives the CY_BLE_EVT_GAPP_UPDATE_ADV_SCAN_DATA_COMPLETE event. This API function must be called when Cy_BLE_StackGetBleSsState() returns the CY_BLE_BLESS_STATE_EVENT_CLOSE state. See the following sample code segment:
if(Cy_BLE_GetAdvertisementState() == CY_BLE_ADV_STATE_ADVERTISING)
{
if(Cy_BLE_StackGetBleSsState() == CY_BLE_BLESS_STATE_EVENT_CLOSE)
{
/* Updating the ADV and SCAN Response data */
cy_ble_discoveryModeInfo->advData->advData[5]='A';
cy_ble_discoveryModeInfo->scanRspData->scanRspData[5]='A';
/* Updating the ADV and SCAN Response data */
Cy_BLE_GAPP_UpdateAdvScanData(cy_ble_discoveryModeInfo);
}
}
