Aina PTT Voice Responder compatibility

[VA2WE]

GM Wes,

Is there a way to have RepeaterPhone work birectionnaly with Aina PTT Voice Responder speaker Mic?

At this time, when connected to a channel, I received audio in Rx but unable to have the Aina PTT Tx.

As mention in a previous tread, I can achieve Rx and Tx with the Inrico B02 perfectly.

It would be great to be able to achieve the same with the Aina PTT Voice Responder.

Thank you if you can bring some insignts.

Regarding speaker mics, they are really two separate devices in one.

1. A "headset"-style device, consisting of a microphone and one or more speakers. These devices all adhere to the Bluetooth Headset Profile (HSP), which means you can easily pair your device and have it appear as an audio input and output because iOS supports this profile out of the box

2. A PTT button that sends a signal over Bluetooth Low Energy (BLE). Because there are zero standards for this, every manufacturer invents their own custom protocol that is unique to their device. I was able to extract a large catalog of Bluetooth devices that Zello supports, to form the foundation of support that exists in RepeaterPhone.

Everything beyond that initial list, I have to code in specific support. That has been a hit and miss proposition. For example, I have yet to get any response back for specs on Irico's latest model. In this case, though, it appears that the company has documented their BLE protocol on their website. That means it's likely that it can work.

However, the next difficulty would be getting one to test with. With the Inrico, I just ordered one off Amazon to develop with, but wowzers,The Aina devices appear to be around $300!

Thank you Weston for sharing your knowledge on the matter. Very informative.

Update on the Inrico B01 and RepeaterPhone App: I confirm it now works perfectly, usage after usage, since I upgraded my iPhone to iOS 18. Fantastic!

As per for the Aina: I understand, expensive device but superior hardware quality and audio performance.

Do not hesite if you want to use me as a beta-tester with speaker mics.
