Soundcore 2 and/or 3 bluetooth disconnect timer...

I’m currently using the Anker Soundcore speaker for playback of accompaniments on the iRealPro app. I’d like a little more power/volume, and am considering purchasing a Soundcore 2 or 3, but I have a question about the bluetooth disconnect timer on these units. Since, for me, there can be gaps of a few minutes between sound signals, I need to make sure that bluetooth will not automatically disconnect too quickly. I’d prefer a disconnect timer time of 10 minutes or more, although 5 minutes would be acceptable. The JBL bluetooth speakers disconnect in 30 seconds without a sound signal, which is unacceptable for my usage.

Does anyone know what the bluetooth disconnect timer is set at for the Soundcore 2 or 3? Thanks in advance.
