# High priority
* platformio sdkconfig CONFIG_PM and turn on modem sleep mode
* finish power measurements and est battery life
* have node info screen show real info (including time since last contact, distance and heading)
* make debug info screen show real data (including battery level & charging)
* make real implementation of getNumOnlineNodes

* keep cpu 100% in sleep (some sort - deep?) Sleep until irq from radio wakes it (make plan based on power draw spreadsheet). Then stay awake for 30 secs to attempt delivery to phone.
* have radiohead ISR send messages to RX queue directly, to allow that thread to block until we have something to send
* use https://lastminuteengineers.com/esp32-sleep-modes-power-consumption/ association sleep pattern to save power - but see https://github.com/espressif/esp-idf/issues/2070

* stop using loop() instead use a job queue and let cpu sleep
* move lora rx/tx to own thread and block on IO
* measure power consumption and calculate battery life assuming no deep sleep
