Soundtouch 300 bluetooth keeps dropping out
I use my phone (iphone 7 & Huawei P30 pro) and iPad air 2 to stream music through bluetooth, and the sound drops every 5 seconds. It does not have this problem when I put my mobile device close enough to the speaker (within 1 foot), over 1 foot, the problem comes out. The speaker becomes useless even it has great sound quality. I have bose solo 15, bose soundlink II, Bose soundsport free, bose on the ear headphone, none of them have any problem. I sent the speaker back to Bose company to fix on September 23, and I got it back 2 weeks ago. When I just got the speaker back, it worked OK, But now, the problem came back. I also tried everything that bose technician told me to do, but it did not work. So, please tell me what I can do now?
