Checksum Incorrect Error in Beta SoniTalk App

Hi,
I tried to send some text using the beta version. Error: CRC Checksum Incorrect was seen many times as I tried sending and receiving. In fact, my experiment couldn't get data over audio even single time. Also, the speaker had to be very close to the microphone of devices to even get an error message.
I recorded video while doing the experiment which can be found in the zip file below.

I really appreciate SoniTalk Project.
Thank you
