A few weeks ago I posted about Red Grid MGRS, a free 10-digit MGRS navigator for iOS (Android shipping soon!). Based on your feedback I shipped a bunch of new updates: Topographic …

Meshtastic has gotten really popular for off-grid texting but I feel like the underlying architecture (LoRa mesh + BLE relay to phone) could do a lot more than chat. I added Meshta…

Most of the conversation around counter-drone is about the defeat side but honestly the bigger problem is coordination. If you have a drone sighting, how do you actually tell someo…

Thank you!

Came across a few online MGRS, lat/lon, UTM, and DMS converters while doing some research for my app. They were covered in ads and none of them supported batch conversions or beari…

Yeah exactly. Apple has a history of quietly changing undocumented behavior between point releases. Building on top of that is asking for a fun debugging session six months from no…

Nice list, thanks. Meshtastic bridge is on the V2.0 roadmap so the app can route through LoRa hardware for multi-kilometer range. Being able to detect and pair with these devices o…

Yes, definitely as a fallback! Currently working on a new build. If you are interested in testing please see the following link to become a tester! https://play.google.com/apps/tes…

Hadn't seen that repo, really interesting find. Using undocumented Continuity fields for discovery is tempting but I wouldn't want to build on something Apple could break in any iO…

Good call, I've looked at Meshtastic's approach. They use CoreBluetooth on iOS with a known GATT service UUID for discovery, which is basically what I'm doing now. The main differe…

I'm building an app that syncs between phones over Bluetooth when there's no cell service. Android has Nearby Connections API which handles discovery and transport nicely. iOS has …

Apologies for posting the incorrect link to the Red Grid MGRS test. Below is the corrected link, thank you for bringing that to my attention! https://play.google.com/apps/testing/c…

If anyone is interested in testing the Android versions, please use the following link: https://play.google.com/apps/testing/com.redgrid.redgridtact... I welcome all feedback. My g…

You're right, I was wrong about iOS 17 auto-negotiating Coded PHY. After digging deeper, Apple did support it briefly in iOS 13.4 betas but pulled it in iOS 14 and it hasn't return…

For the time being yes, I am looking for Android testers (need 12 to publish and I am a solo dev), if you are interested please reach out!

Thanks you! Just started working on this project based on systems I use, and have gripes with, in the military. No plans to abandon it, but I understand your concern. This is the p…

If you ever do get the chance to use, let me know what you think!

All true, but the tradeoff is zero additional hardware cost and zero setup. For a family hike, small team, or a hunting party staying within a few hundred meters of each other, pul…

Yeah iOS supports BLE Coded PHY since the iPhone 12 / iOS 14. The tricky part is negotiating it at the library level. flutter_blue_plus doesn't fully expose Coded PHY yet so I'd ne…

Thank you! Would love some feedback if you try it out!
