I just want to send a message just like string/number into the NXT from my Android. But NXT didnt receive the data. I use ROBOT C for NXT program and BluetoothMessage example from the ROBOT C.
First, I try source code for Android from Bluetooth-connection between Android and Lego Mindstorm NXT. But didnt work.
Then I download a software from Google Play, NXT Mailbox and it works.
Does anybody has a source code for Android to send message into NXT ?
