Bluetooth in crowded places - tursiops - 2025-07-17
Hi all,
I started using my tangara with bluetooth while taking the train every day but I noticed that while the bluetooth quality and stability is very good and i'm alone at home, it goes completely unusable when I go to a crowded train station, even if i'm just waiting by the platform next to the train tracks, I get static and overall music stutters.
Is this something to do with my headphones ? I'm using bose qc ultra. Or it is something else ?
Thank you,
Rafael.

I'd try with another set of headphones if you can, to see if it improves. I've used a few different bluetooth headsets in crowded areas without any issues, and from my experience with my own Bose QC35's they can be a bit temperamental with the connection compared to my other ones.

I've used Sony WF-1000XM5 (earbuds) and Sony WH-1000XM3 (over-ear headphones) and both suffer from the same problem. I have to keep the tangara in a banana bag around my chest in order to not have any drop outs. Walking with the player in hand is also OK, but when I put it in my pocket I'll get drop outs. In busy places it's completely unusable from in a backpack or trouser pocket. In the countryside it's a lot better but will still drop out from time to time.
I've opened up the tangara and noticed it uses the built-in antenna of the ESP32. There is a version that can accommodate an external antenna, you can also modify the one used to add an external antenna, but I'm not sure if that would help. I've asked here but nobody seems to have any advice.

Is this with the latest firmware by the way? There have been some bluetooth signal improvements made since 1.3.0 so that is worth trying if you've not upgraded the firmware yet.

I've been running v1.3.4 since it's release. I've thought of boosting a bit more by adjusting https://codeberg.org/cool-tech-zone/tangara-fw/src/branch/main/src/drivers/bluetooth.cpp#L541 but haven't tried it.

I have QC Ultras too and they're *mostly* fine with my Tangara, but my phone ('22 Motorola Razr) hates my headphones and if I even have its bluetooth turned *on* (not connected to the headphones) in the vicinity of the tangara it degrades the otherwise fine connection
