error response : Insufficient Authentication

[Woody Hung]

I combined ble_app_hrs of example with ble_app_hts of example .

I write command in client characteristic configuration,
there is a problem that ATT_ErrorRsp : status = 0 oc=0x0012 h=17 error=5,

What's wrong with it ?

Thanks!!

Just like Petter Myhre said in this case, you most likely need to pair. This will then encrypt the link.
