AVR Freaks

Finally solved my problems.

I could wake the ble_event_task from AO_GPIO using a platform event, but it would work only once and then crash the mcu.

My problem was that I was using ble libs without actually registering any ble services. Once I implemented the iBeacon service the ULP and platform events worked without problems

I did multiple things (always smart) so I do not know what fixed it in the end. But the basis is actually adding a service..

For iBeacon this is 

status = at_ble_adv_data_set((uint8_t *)adv_data, sizeof(ro_adv_data), (uint8_t *)scan_rsp_data, sizeof(ro_scan_rsp_data));

status = at_ble_adv_start(AT_BLE_ADV_TYPE_UNDIRECTED, AT_BLE_ADV_GEN_DISCOVERABLE, NULL, AT_BLE_ADV_FP_ANY, 16000, 0, 0);

(please see the atmel example for ibeacon for the rsp/adv data)

I also used 

ble_mgr_events_callback_handler(REGISTER_CALL_BACK, BLE_GAP_EVENT_TYPE, beacon_app_gap_cb);

ble_mgr_events_callback_handler(REGISTER_CALL_BACK, BLE_GATT_SERVER_EVENT_TYPE, beacon_app_gatt_server_cb);

to handle the events. Most of the handlers are empty (and return AT_BLE_SUCCESS)

Special one is

static at_ble_status_t ble_disconnected_app_event(void *param)

which contains :

at_ble_adv_start(AT_BLE_ADV_TYPE_UNDIRECTED, AT_BLE_ADV_GEN_DISCOVERABLE, NULL, AT_BLE_ADV_FP_ANY, 16000, 0, 0);

To restart the advertisement (note I have used a very long time between advertising)

I've also added

register_ble_user_event_cb(platform_event_cb);

with implementation

static void platform_event_cb(void)

{

platform_event_get(&plf_event_type, plf_event_data, &plf_event_data_len);

}

Of all these things the actual adding/start advertisement was the real fix, but the others things make for better code ;)
