I'm playing with open-source IoT over Bluetooth and recently was told about TI's new SensorTag product line which uses a CC2650 multi-sensor bluetooth base platform with pluggable display/actuator modules in a deployable form factor.
Is anybody doing something like this with Nordic nRF51 (or maybe nRF52) hardware? The only thing I've found is the LinkSprite BLE_SENTG which is a great start but it's just the populated runnable board and isn't deployable by a software-oriented solo maker without finding some sort of protective case.
