iPhone SE: Mic from Lightning to Bluetooth speaker?

Three things I can tell you. The latency will be more than you’re probably thinking. The iPhone system natively won’t do it. A mixer will need to be used. If you want a more detailed explanation please let me know.

Thanks for your feedback so soon! But that is the kind of wireless lavalier

microphone I am trying to use. (With a microphone transmitter and receiver plugged into my iPhones lightening contact.) The loadspeaker I have is a portable wireless speaker (Charge mini).

Having these bluetooth connections I thought this would be a handy way of

getting a simple and lightweight amplifying of some extra decibels, with super low latency, for singing and guitar. Professional cable-free equipment seems to cost a lot, and having traditional cables keeping you bound to even a small loadspeaker is inconvenient.

I wonder if I need to alter something in the iPhone's Settings, or if the App Store has some help for getting the iPhoneSE to send the sound directly from the microphone receiver via the Bluetooth to the wireless loadspeaker?

Sorry for this long explanation, but if it would work I think it could be of great use for loads of people. Thanks again!

Sorry, but I just don't have any experience with what you're trying to do. I've been on this forum daily for many years, and you're use case for this is the literally the first I've ever seen. You can reach out to Apple directly, but I suspect what you're looking to do isn't supported on iPhone.

When your wireless lav talks to a Bluetooth receiver and that receiver is paired to the iPhone, iOS treats that as a full Bluetooth audio device with a linked input and output. If you select the Bluetooth device as the input (mic), iOS also wants to use that same device as the output, by design. iOS does not support using a Bluetooth input profile and a different Bluetooth output profile (or a second Bluetooth speaker) at the same time.

So there’s no system-level way to say: “Use this Bluetooth lav/receiver as my mic and send that live audio out to a separate Bluetooth speaker” the way you might on a mixer.

I would think the microphone would have to be Bluetooth capable, like some of the options you can see here --> https://www.amazon.com/s?k=bluetooth+microphone+with+lightning+connector+for+external+speaker&crid=3C6AXQL4W9GUX&sprefix=bluetooth+microphone+with+lightning+connector+for+external+speaker%2Caps%2C126&ref=nb_sb_noss
