### INSERT COIN window for individual coinslot
In individual mode the board can wait for the phone's INSERT COIN tap before accepting coins.
- Coin Accept stays off until the customer taps INSERT COIN on the bound phone
- The board beeps and opens the coinslot for 30 seconds
- Each coin restarts the 30 seconds
- Warning beeps in the last 5 seconds, then the coinslot closes again
- Closes early if the phone leaves the screen or disconnects
- Turned on from the phone (Require INSERT COIN tap). Needs PisonetX Launcher 4.6.4 or newer
- With Launcher 4.6.3 or older, coins are accepted as in 2.9.3

### Flashing

- The same file is safe for every unit. It contains no WiFi, password or device ID
- The full image overwrites the settings area, so run Setup New Vendo again after flashing
- If the upload fails at 921600 baud, use 115200
