Hardware Power Management
PandwaRF is shipped in shutdown mode.
If it is the first use after unpacking the device, you need to wake up PandwaRF.
PandwaRF will awaken if a button is pushed or if USB is plugged in.
To wake up PandwaRF :
- Preferred method: Plug PandwaRF onto an USB power source (the Orange & Blue lights will blink slowly to indicate charging & BLE advertising), or
- Alternative method: Open the plastic enclosure and press any button (the Blue light will blink slowly to indicate BLE advertising).
Starting at Rev.F, the SW5 power switch is now a ON/OFF power switch replacing the reset push button. If your PandwaRF LEDs are off even while powered with USB, you should open the enclosure and check that SW5 switch is in the ON position.
Several LEDs are used to indicate power status. Cf. LEDs Indication States
- While charging, the orange LED will blink slowly.
- When charged, the orange LED remains on.
When not plugged onto USB and not connected in BLE, PandwaRF enters low power mode and only advertises to allow BLE connection.

In case you need to shut down PandwaRF completely, you can:

Warning: in this mode, your smartphone will not be able to discover or connect to your PandwaRF.
Pressing any of the 5 buttons will wake up the PandwaRF.
PandwaRF has an integrated Battery Gas Gauge, allowing to precisely measure the remaining battery capacity. For the measurement to be precise, PandwaRF needs to be fully charged at least once. It will then initialize its coulomb counter to 100%. Once unplugged from power source, it will start monitoring its own consumption.
