Chatter not receiving/sending msg

Hi,
Just finished build this with my kid and we are having problems with it.
Sometime msg get through, in the same room, but more often they are not sent/received. The circle remains “unfilled” even after resend.
Any hints of what could be? They pair ok, but only some few messages get through.

Thanks
P

Hello @Pedro_Farinha,

Could you let us know if the issue happens even when the devices are in different rooms, same room or just in this specific room?

Also, please send us photos of the soldering points on both devices via email at contact@circuitmess.com so we can take a closer look and help troubleshoot further.

Looking forward to your reply!

Kind regards,
