DESCRIPTION:Flamingo is a specialized cave and confined-space communication
 s system derived from Meshtastic and optimized for SAR or expedition opera
 tions. The goal of Flamingo is to provide a reliable system that is versat
 ile\, efficient\, and substantially cheaper than alternative commercial sy
 stems.\n\nBuilding off of the work done by Vangelis\, we currently have cu
 stom “Cavenode” and “Hybrid” nodes that are compatible with other 
 commercial radios. Both node types function as relays or personnel radios 
 in rugged\, water-resistant enclosures. Cavenodes include an integrated bu
 zzer for feedback during hands -free setup\, while the Hybrid adds a large
 r folding antenna and an RS485 link for wired digital comms.\n\nAll Flamin
 go radios are based on the RAK4631 LoRa module with a WisBlock baseboard a
 nd can operate for approximately 10–14 days on a single 18650 Li -ion ba
 ttery. Modifications made to Meshtastic include expanding the hop limit fr
 om 7 to 255 hops\, optimizing for a chain topology but providing for a reg
 ular mesh. Hybrid nodes allow seamless bridging between both RF links and 
 traditional cave comms phone wire with the RS485 module.\n\nFlamingo has b
 een tested in caves and operated during multiple mock rescue exercises wit
 h the HCRU. We ’ve demonstrated 16 hops with under two minutes of latenc
 y among 20+ nodes. We ’ve demonstrated mixed wired/ wireless networks ex
 ceeding 4\,500ft of distance in multiple exercises. Recently operational t
 est kits have been delivered to HCRU and other partners. Additional improv
 ements include a hands -free setup mode and a method for syncing batches o
 f radios’ settings.
