BLECharacterstic.setValue() overrides to allow additional data types

jrickard · jrickard · commit bbec0b9793dc · 2018-04-07T14:10:04.000-05:00
Revised BLECharacterstic.setValue() to allow additional data types when
setting characterstic values.

Added for uint16_t, uint32_t, int, float, and double.

These data types appear to carry through to iPhone examination of ESP32
BLE transmission.
