+- possibly switch to https://github.com/SlashDevin/NeoGPS for gps comms
 - good source of battery/signal/gps icons https://materialdesignicons.com/
 - research and implement better mesh algorithm - investigate changing routing to https://github.com/sudomesh/LoRaLayer2 ?
 - check fcc rules on duty cycle. we might not need to freq hop. https://www.sunfiretesting.com/LoRa-FCC-Certification-Guide/

 * DONE read about mesh routing solutions (DSR and AODV)
 * DONE read about general mesh flooding solutions (naive, MPR, geo assisted)
 * DONE reread the disaster radio protocol docs - seems based on Babel (which is AODVish)

+* possibly dash7? https://www.slideshare.net/MaartenWeyn1/dash7-alliance-protocol-technical-presentation  https://github.com/MOSAIC-LoPoW/dash7-ap-open-source-stack - does the opensource stack implement multihop routing?  flooding?  their discussion mailing list looks dead-dead
 * update duty cycle spreadsheet for our typical usecase
 * generalize naive flooding on top of radiohead or disaster.radio? (and fix radiohead to use my new driver)
