indication to notification in ble HTS profile

[Ankush]

Hi,

I am new to the BLE profiles. I am have to send the TMP007 temperature sensor values to mobile APP using BLE HTS profile. for this I am using sample example of nrf52 SDK 11.0.0.

When I am running the sample example without any changes i am not getting the default values of temperature.When I am enabling the indication it is saying "GATT INSUF AUTHENTICATION".

so i want to change the indication to notification so that as soon as enable notification it should send continuous vales.

Can anyone help me in this regards?? is it required to enable timer for continuous data?

In services_init() you can see that the security level for link has to be 2 (Unauthenticated pairing with encryption, but no MITM protection) to be able to write to the CCCD (enable ind/not):

BLE_GAP_CONN_SEC_MODE_SET_ENC_NO_MITM(&hts_init.hts_meas_attr_md.cccd_write_perm);

Try to pair/bond first, then you should be able to write to the CCCD.
