Recently we have been asked by customer .i can use FeasyBlue app for data transmission ,it works.why i would like to use the bluetooth of cellphone directly,it does not works ,why ?
If you use a cellphone ,then enter ‘’bluetooth'',you can see there is a bluetooth device list .
I have to mention that if audio device such as,audio bluetooth module ,bluetooth speaker ,bluetooth earphone ext,we can find the bluetooth name ,tap it then can auto pair .
If you want to pair it is a data module only ,so you have to use app such as FeasyBlue app for send and receive data .
For more details ,feel free to Contact Feasycom .
