#### Device sleep period
To use as little power as possible while running on battery, ESP32 based devices go into a sleep mode. Unfortunately, during this sleep mode they turn off their Bluetooth radio. They can be woken early from this sleep by either receiving a message over LoRa (the LoRa receiver never switches off), of by pressing a program button where there is one on the device. This setting allows the length of the sleep mode to be changed from the default of 300 seconds (5 minutes). To keep the bluetooth link alive for eight hours (any usage of the bluetooth protcol from your phone will reset this timer), set this to 28800 seconds.
By default, ESP32 devices will enter sleep mode after 300 seconds of inactivity to save battery power. Unfortunately, this will also turn off the Bluetooth radio. They can be woken by either receiving a message over LoRa (the LoRa receiver never switches off), or by pressing a program button when there is one on the device. For example, to keep the Bluetooth link awake for eight hours (any usage of the Bluetooth protocol from your phone will reset this timer), set this to 28800 seconds.
