Send txt file to another Android device through bluetooth

I read lots of posts about bluetooth but I didn't find answer.

I juste want to send a text file from a device (A) to an other one (B) using bluetooth.
I don't want to install specific app on device B the file has to be received in standard Android BT app.

All ways i found to send data from a devive to an other is using client and server which need to install an app on device B

maybe using ActivityStarter, but then how specify it which file to send and to which device ?
