Murmur : Bluetooth Group Calls

Update: Iphone 14 pro max, IOS 18.6.2, SUOOKC headset from Amazon for both. My gf and I are on the same motorcycle. After some time, the circles get further away from each other and the call drops intermittently. It will regain but seems very unpredictable. I paid for the full version on both phones because I like the idea and I hope this gets fixed

Murmur is an incredibly well-designed app that does something most people don’t realize is possible: real-time group audio over Bluetooth mesh, with no internet or centralized infrastructure. The implementation is rock solid—audio stays clear, latency is impressively low, and the mesh routing actually extends range in a meaningful way. I’ve used it on hikes with friends spread out along the trail, and it just works. It’s the kind of tool that feels both technically elegant and genuinely useful. I’m glad this exists—it fills a real gap in offline communication.

Used this with passenger on motorcycle. When it works it’s really nice and a cheap alternative to cardo. But: Trying to play music just completely stops the call. Also overtime it creates its own feedback loop then loses connection with passengers phone it seems like it’s real easy to pick up on 2.4ghz/bluetooth interference at one point I was hearing audio from some device that wasn’t either of our phones it sounded like really really muffled radio music. It’d be nice to have a more secure channel that didn’t have that issue. It’s really hard to mess around with and restart the app on both phones while riding a motorcycle so we ended up just not being able to talk for the last 30 min of our ride. Please add: -Auto Healing connection so you don’t have to try and fix it while doing your activity -maybe channel hopping? I know some LE voice systems will automatically switch around to whatever channel has the least interference. That would be really nice.
