Advertising timeout and low power advertising with latest CubeMX
I'm having an oddly difficult time seeing how to do something quite simple. In older CubeMX projects, the `Adv_Request` function looked like this:
static void Adv_Request(APP_BLE_ConnStatus_t NewStatus)
{
tBleStatus ret = BLE_STATUS_INVALID_PARAMS;
uint16_t Min_Inter, Max_Inter;
if (NewStatus == APP_BLE_FAST_ADV)
{
Min_Inter = AdvIntervalMin;
Max_Inter = AdvIntervalMax;
}
else
{
Min_Inter = CFG_LP_CONN_ADV_INTERVAL_MIN;
Max_Inter = CFG_LP_CONN_ADV_INTERVAL_MAX;
}
/**
* Stop the timer, it will be restarted for a new shot
* It does not hurt if the timer was not running
*/
HW_TS_Stop(BleApplicationContext.Advertising_mgr_timer_Id);
if ((NewStatus == APP_BLE_LP_ADV)
&& ((BleApplicationContext.Device_Connection_Status == APP_BLE_FAST_ADV)
|| (BleApplicationContext.Device_Connection_Status == APP_BLE_LP_ADV)))
{
/* Connection in ADVERTISE mode have to stop the current advertising */
ret = aci_gap_set_non_discoverable();
if (ret != BLE_STATUS_SUCCESS)
{
APP_DBG_MSG("==>> aci_gap_set_non_discoverable - Stop Advertising Failed , result: %d \n", ret);
}
else
{
APP_DBG_MSG("==>> aci_gap_set_non_discoverable - Successfully Stopped Advertising \n");
}
}
BleApplicationContext.Device_Connection_Status = NewStatus;
/* Start Fast or Low Power Advertising */
ret = aci_gap_set_discoverable(ADV_IND,
Min_Inter,
Max_Inter,
CFG_BLE_ADDRESS_TYPE,
NO_WHITE_LIST_USE, /* use white list */
sizeof(a_LocalName),
(uint8_t*) &a_LocalName,
BleApplicationContext.BleApplicationContext_legacy.advtServUUIDlen,
BleApplicationContext.BleApplicationContext_legacy.advtServUUID,
0,
0);
if (ret != BLE_STATUS_SUCCESS)
{
APP_DBG_MSG("==>> aci_gap_set_discoverable - fail, result: 0x%x \n", ret);
}
else
{
APP_DBG_MSG("==>> aci_gap_set_discoverable - Success\n");
}
/* Update Advertising data */
ret = aci_gap_update_adv_data(sizeof(a_ManufData), (uint8_t*) a_ManufData);
if (ret != BLE_STATUS_SUCCESS)
{
if (NewStatus == APP_BLE_FAST_ADV)
{
APP_DBG_MSG("==>> Start Fast Advertising Failed , result: %d \n\r", ret);
}
else
{
APP_DBG_MSG("==>> Start Low Power Advertising Failed , result: %d \n\r", ret);
}
}
else
{
if (NewStatus == APP_BLE_FAST_ADV)
{
APP_DBG_MSG("==>> Success: Start Fast Advertising \n\r");
/* Start Timer to STOP ADV - TIMEOUT - and next Restart Low Power Advertising */
HW_TS_Start(BleApplicationContext.Advertising_mgr_timer_Id, INITIAL_ADV_TIMEOUT);
}
else
{
APP_DBG_MSG("==>> Success: Start Low Power Advertising \n\r");
}
}
return;
}
However, in the latest code generated by CubeMX, the function now looks like this:
static void Adv_Request(APP_BLE_ConnStatus_t NewStatus)
{
tBleStatus ret = BLE_STATUS_INVALID_PARAMS;
BleApplicationContext.Device_Connection_Status = NewStatus;
/* Start Fast or Low Power Advertising */
ret = aci_gap_set_discoverable(ADV_TYPE,
CFG_FAST_CONN_ADV_INTERVAL_MIN,
CFG_FAST_CONN_ADV_INTERVAL_MAX,
CFG_BLE_ADDRESS_TYPE,
ADV_FILTER,
0,
0,
0,
0,
0,
0);
if (ret != BLE_STATUS_SUCCESS)
{
APP_DBG_MSG("==>> aci_gap_set_discoverable - fail, result: 0x%x \n", ret);
}
else
{
APP_DBG_MSG("==>> aci_gap_set_discoverable - Success\n");
}
/* USER CODE BEGIN Adv_Request_1*/
/* USER CODE END Adv_Request_1*/
/* Update Advertising data */
ret = aci_gap_update_adv_data(sizeof(a_AdvData), (uint8_t*) a_AdvData);
if (ret != BLE_STATUS_SUCCESS)
{
APP_DBG_MSG("==>> Start Fast Advertising Failed , result: %d \n\r", ret);
}
else
{
APP_DBG_MSG("==>> Success: Start Fast Advertising \n\r");
}
return;
}
In my application, I would like to have the device start in fast advertising mode, and after 30 seconds, change to low power advertising. This is what examples like the `BLE_HeartRate` example do, but these examples all seem to use the older version of `Adv_Request`.
I could certainly hack this in myself, but I would prefer to see an example from ST showing how the new function should be used to accommodate the same functionality. I assume ST had something in mind when this change was made, and rather than trying to work against that vision, I would prefer to work within it where possible.
Is such an example available?
