I am using devices managed by WMP100. I have two devices connected each other by bluetooth (W12 Bluegiga). I am using FCM service to send commands and data to the bluetooths.
My question is: Have to be in “command mode” to get response from device which I send data?
Because…When I am sending “command” in “command mode” I get response, but when I am sending data in “data mode” despite I should get some data in response I don’t. Then when I change mode to “command” I get this reponse.
I was thinking that shuld get response without changing mode. So where is the truth?
Thanks for all help
