Where to find a health thermometer central device

[Rbai]

In the examples delivered by Nordic, there is ble_app_hrs in ble_peripheral and ble_app_hrs_c in ble_central. But I cannot find a ble_app_hts_c in ble_central for the ble_perifpheral/ble_app_hts.

Is it available somewhere?

Unfortunately, we don't have a hts_c example available.

I started writing the ble_app_hts_c. I copied the ble_app_hrs_c and made some name changes. I don't expect the whole thing work without significant changes, but I am expecting it can at least scan and get the advertisement from the HTS server. But it never stops at ble_hrs_on_db_disc_evt() function, where UUIDs of the service can be seen. Can you give me some pointers on how to convert the hrs_c to hts_c? What needs to be done to scan the HTS? Thanks.

The first thing you should do is to examine how the BLE_GAP_EVT_ADV_REPORT event is handled.

I was able to get pass the scanning and GAP connection. But service discovery was not successful. Th NUS example shows that I need to do the service discovery after getting the BLE_GAP_EVT_CONNECTED event. But the HRS_C is doing the service discovery under a different place in DM_EVT_LINK_SECURED. Why it is different?

Another issue is that the Keil debugger "Call Stack + locals" shows not in scope for some variables, which is in scope. Is that a known issue?

Have you registered the hts UUID with ble_db_discovery_evt_register()? You can choose when to do service discovery, it seems hrs_c is bonding first, while uart_c does service discovery first. Maybe it has something to do with optimization? Set Options for Target->C/C++/Optimization to Level 0. Does it help?
