Re: BLE Disconnection problems

Certainly seems like an electrical problem. You would want to shield the nrf51 chip from the noise somehow, but how do to that is out of my area of expertise. You might try asking on the Nordic forum.

Re: LCD devpack

I'm afraid the documentation mentions no such capability in the screen's default firmware. To add new features, you would have to modify the firmware, presumably by using their "BLE-STACK V2.1".

Re: LCD devpack

The docs say Display Data size is 1-16 bytes. "Hello World Test!" is 17 bytes. Try a shorter string.

Re: LCD devpack

Looks like the SensorTag doesn't have the characteristic "f000ad02-0451-4000-b000-000000000000", as I thought it would. The documentation only says "ad02", so we'd have to guess at the rest of the UUID... except you can use the BLE Discovery example to get a complete list. So do ...

Re: Phonegap with sample apps in Evothings

I suspect "cordova-plugin-bluetoothle" and "com.evothings.ble" will conflict with each other. Suggest you pick only one of them.

Re: How to turn on sensor from application ?

When using our tisensortag library, it's as easy as saying "On" or "Off" for the sensor of interest. See an example.

Re: BLE or classic

No, it is quite different. You scan for devices in a similar manner, but with BLE you can get extra advertising data. (It is this advertising data that is used to create the Beacon protocols.) You can pair and connect to devices in a similar manner, but once connected things become different. Classi...

Re: How to interpret data coming from the pedometer device

Like I said, I would hope they're running the standard Running Speed and Cadence service. They might also provide the Heart Rate and Pulse Oximeter services.
