5 years ago Hello, the log line 2018-11-09 02:08:13,999 [1] DEBUG MGT.HRM.HRP.BtHrp - Getting HeartRateMeasurement GattCharacteristic 1 2018-11-09 02:08:14,006 [1] WARN MGT.HRM.HRP.BtHrp - Error configuring HRP device System.ArgumentOutOfRangeException: Specified argument was out of the range of valid values. Parameter name: index at System.Runtime.InteropServices.WindowsRuntime.IVectorViewToIReadOnlyListAdapter.Indexer_Get[T](Int32 index) at MGT.HRM.HRP.BtHrp.d__77.MoveNext()
means that the BTLE api could not lookup a HeartRateMeasurement characteristic on the device.
The 1-16 setting in cardia is just for selecting between multiple characteristics of the same type (HeartRateMeasurement) detected on the device, 1 should always work. It would be interesting to do a log of the full scan of characteristics supported on the device, i might include it.
The error 2018-11-09 02:24:29,130 [1] WARN MGT.HRM.HRP.BtHrp - Error configuring HRP device System.NullReferenceException: Object reference not set to an instance of an object. at MGT.HRM.HRP.BtHrp.d__77.MoveNext()
seems to be the result of some not clear state from the previous run, i will also try to put a log to track it down.
Btw, what windows version (including the build) are you running?

Hey, thanks for making the cool application! I'm trying to get it to work with my Wahoo TICKR. However, it's not going smoothly. Log is below:

Not wanting to send you down a rabbit hole, I found a program called Bluetooth LE Explorer. I'm not sure if it's using the same API, but when querying my TICKR it showed that HeartRate was characteristic 35, but that the value is "Read Not Permitted". I also noticed that Cardia can only accept characteristics 0-16. I tried characteristic 13, which should be BatteryLevel, but that didn't work either. Here's the log from your test program when trying that:

Any chance you know what's going on? It would be great if it's an easy fix.
