Are you using any specific application to do the file transfer?
Thanks for the reply.
I am using just CYSPP application which is their already with EZ serial firmware.
I am facing problem in BT classic mode. I will pair the device with bluetooh setting and then I will use my company's app for application purpose. when I want to use next time the same device, I thought I can directly use my company's app since it is already paired. But when I do so, I will get a message saying that I should pair it again.
But I tested with HC05 device, once it is paired then it will not ask again and again to pair it.
So I require this pairing should be remembered from my android device. How can I do it?
Does the problem happen if you reset the module or power cycle it?
Do you test the problem with other APP?
I test it on my phone with a SPP APP and don't see the problem after reset or power cycle.
It happens when I supplied the power.
I did it with SPP also. But when ever I power the module it always says to pair again.
Is it to do with the app??
Could you check if the device is in the bonding list of your phone after the connection?
