Hello,
I'm trying to make a low power device with ST BlueNRG-LP (455M).
I have an incomprehensible error with the BLE.
I set BLE advertising with advertising data and scan response every 10 seconds (adv_interval=10000).
ret = aci_gap_set_advertising_configuration(0, GAP_MODE_GENERAL_DISCOVERABLE,
ADV_PROP_CONNECTABLE|ADV_PROP_SCANNABLE|ADV_PROP_LEGACY,
(adv_interval*1000)/625,(adv_interval*1000)/625,
ADV_CH_ALL,
NON_RESOLVABLE_PRIVATE_ADDR,NULL,
ADV_NO_WHITE_LIST_USE,
0, /* 0 dBm */
LE_1M_PHY, /* Primary advertising PHY */
0, /* 0 skips */
LE_1M_PHY, /* Secondary advertising PHY. Not used with legacy advertising. */
0, /* SID */
0 /* No scan request notifications */);
After this I set advertisement data and scan response
ret = aci_gap_set_advertising_data(0, ADV_COMPLETE_DATA, sizeof(BLE_AdvertisementData), BLE_AdvertisementData);
ret = aci_gap_set_scan_response_data(0, sizeof(BLE_AdvertisementData2), BLE_AdvertisementData2);
Then I enable advertising
BLE_Advertising_Set_Parameters[0].Advertising_Handle = 0;
BLE_Advertising_Set_Parameters[0].Duration = 0;
BLE_Advertising_Set_Parameters[0].Max_Extended_Advertising_Events = 0;
ret = aci_gap_set_advertising_enable(ENABLE, 1, BLE_Advertising_Set_Parameters);
Everything is working until this point.
After some time I update advertisement data and scan response, it's working too.
After a long and not constant time, the device stop advertising. (many hours)
When the device is not advertising anymore, if an "advertising reset" I received the error 0x07 and my device reset.
ret = aci_gap_set_advertising_enable(DISABLE, 0, BLE_Advertising_Set_Parameters);
OK
ret = aci_gap_set_advertising_enable(ENABLE, 0, BLE_Advertising_Set_Parameters);
ret = 0x07 => BLE_ERROR_MEMORY_CAPACITY_EXCEEDED
Some important precision, BlueNRG-LP is working on a battery CR2430 with a max current of 4mA. The board is draining 4.5mA from this battery when ON and the voltage drop to 2.7V
I have some question:
- Can you check "handle" and "Number_of_Sets" ?
- Do you have any idea of why I have this error ?
Thank you
