Bluetooth Not Responding


#1

Hi, I recently purchased an “ultimate robot kit”. I’m able to upload simple programs to the Orion board and run them. I’m also able to connect over bluetooth from my laptop to upload code.

I’ve been trying to use my Samsung Galaxy S7 phone to control the robot however I cannot get this to work. My phone pairs and connects to the bluetooth module just fine. The BLUE LED stays solid blue indicating there’s a connection. But when I try send commands from my phone nothing happens. I tried the “robot tank” example, along with just adding M1 and M2 to a new project. Nothing works.

Am I missing something there? Does the robot need some base code for the bluetooth module to work?

I solved the problem myself.

it was a 2 part problem. First part is that I had the bluetooth module plugged into the wrong port on the Orion… I failed to notice the “gray/blue” symbol. After that, the problem still persisted… so I compiled the “ultrasonic example” from the makeblock library and compiled it to the robot. Now my bluetooth controls are working from both my computer and from my cell phone!

Now to learn more programming… I hope this helps someone else.
