Simple iOS app that automatically finds, connects to, and sends a command through a private protocol to play an onboard sound effect on JBL speakers.
You can find the .ipa for the app in the releases. To run it, sideload it onto an iOS device running iOS 15.5 or up and follow the on-screen instructions. Make sure your speaker is turned on and connected to the device before you open the app.
I don't really know. I found a cool discussion pannel about the communication protocol for JBL's older speakers (pre-partyboost, I don't think those ones work with this app) and wanted to utilize a Swift app to send one of the commands. Check it out here!
