I have been looking around for a demonstration of someone using the ASHA feature on an android phone, but a general google search only brings up ASHA feature being announced (from 2018) or something link this (https://www.youtube.com/watch?v=u7ZDzqC3Mak) which shows how to connect an android capable hearing aid to an android smartphone using their custom app.
I believe that ASHA feature being integrated into Android means I should be able to pair with a hearing aid without need for a custom app (correct me here if I am wrong). I have an embedded system development board which claims it can work as BLE device with an ASHA capable smartphone. I also have a Samsung Galaxy s10e which is supposedly ASHA capable (cannot find any official source confirming this, but lots of online discussions imply that s10e series supports ASHA, as well as there are some options in settings which makes me think it probably is). One of the only hearing aids in the market that supposedly uses ASHA claims it supports direct streaming with galaxy s10e phones (https://www.resound.com/en/help/compatibility).
If I go to Settings > Accessibility > Hearing Enhancements > Hearing Aid Support > Bluetooth Hearing Aid in my Samsung Galaxy s10e, I can see that it allows me to pair with my custom BLE device (which supposedly has BLE 5.0 and supports BLE audio streaming with android). However, if I play music on the phone after pairing, I cannot hear any output on the built in speakers, but I cannot hear anything in my BLE device either. It’s possible that at this moment the BLE device does not have the required codecs for audio streaming, but that is a different question.
My main question is about ASHA streaming on the android phone. Am I correct in assuming that after pairing with my BLE device by going to Settings > Accessibility > Hearing Enhancements > Hearing Aid Support > Bluetooth Hearing Aid, I should be able to hear audio played on my phone from the BLE device, like I would on a regular bluetooth earphone? I haver been searching online for at least a demonstration of ASHA streaming or how the Bluetooth Hearing Aid support on the galaxy s10e is supposed to be used, but I cannot find anything. Does anyone here have any experience with this?
