ble_hts_is_indication_enabled always false on re-connection

[ppatierno]

Hi,

I'm developing a peripheral that expose the HTS service. I have the on_hts_evt event handler to handle BLE_HTS_EVT_INDICATION_ENABLED and BLE_HTS_EVT_INDICATION_DISABLED to start and stop a timer that sends temperature value. Suppose I enable indication from central side (a smartphone) ... it works great ... the indication is enabled and the temperature value is received (on the central). Suppose I disconnect from peripheral without disabling indication first. When I reconnect, handling the DM_EVT_LINK_SECURED event in the device_manager_evt_handler event handler, I use the ble_hts_is_indication_enabled to check if indication is enabled (I get the code from ble_app_hts example). However, the above function returns always false even if as I said I disconnected from peripheral without disabling the indication.

Why ?

Thanks, Paolo.

Hi Paolo,

It's normal that the function return code was false (0) because 0 = NRF_SUCCESS. Meaning the function returns successfully.

The output of the function is the value of "is_indication_enabled" not the return code of the function.

Sorry I wasn't so precise ... I mean the second input/output parameter with "is indication enabled value"

My test here showed that is_indication_enabled = 0x01. Could you double check ? Do you have the indication after you reconnect and press the button ?

[ppatierno]

what's the button you are talking about ?

I have the following code :

err_code = ble_hts_is_indication_enabled(&m_hts, &is_hts_indication_enabled);

in the DM_EVT_LINK_SECURED event handling but this event isn't raised when the smartphone in already bonded with peripheral. To have this event raised I need to "forget" peripheral on smartphone (it's Android) but I think that in this way I lost indication status on peripheral or not ? What's the right way the things work ?
