Hi Few days ago, at my office, I developed a program on a tablet using bluetooth to connect and exchange information with another devide and everything worked perfectly. Some days later, in a big exhibition, I tried to make the pairing between both devices but I was not successful, it took me 1 hour to realize that the big number of devices that the tablet discovered caused a big interference between the tablet and my device even though both devices were next to each other. I left the showroom and the pairing and the exchange of information were perfect. How can I fix this problem? is there something to limit the search for bluetooth decives to pair? Has anyone had this problem? My tablet works as slave and my other device as Master.
