The EFR32xG22E kit sends out BLE packets every 25 seconds with the capacitor’s voltage.
The voltage is stored as two hexadecimal bytes in big-endian format, within the packet’s Manufacturer Specific Data field. To read the voltage, simply convert these two bytes from hexadecimal to a number.
For example, if the data is: “0x0BA5”
