Sending a packet through a WiFly

Wireless & IoT
1

So I’ve got a wifly rv-xn configured to 10.0.1.13 and properly joined to my wifi network. I can telnet to it fine.

The TX of the wifly is connected to the RX of a Micro Maestro serial servo controller. I am trying to send that MM board the following 4 bytes: 132, 0, 112, 46.

I can tell the wifly is getting the bytes from its indicator LEDs. DOut flashes when I hit return after each byte in my telnet client (which is Terminal on OSX, if that helps).

The Micro Maestro is not showing a received byte (its LEDs don’t flash like they should). Can anyone help with what is going wrong here? I could also send a packet using curl, I think. Would that look like “curl http://10.0.1.13 132 0 112 46”? Because that doesn’t work either.

I’ve done the basics, like verifying that the MM works and can control a servo when hooked up to the computer with USB using their demo software.

Thanks.

Check your baud rates are the same as the wifly. Its default rate is 9600 . You can set higher baud rates in command mode.

Also, check you have a common earth with the wifly device and the device you are sending packets to and from.

And also check that the reciever is 3.3v tolerant on the rx / tx pins like the wifly.
