I'm trying to send some commands via BlueSMiRF HID module.
I can send this...
Serial.write(0xFD);
Serial.write(0x03);
Serial.write(0x03);
Serial.write(0x80);
Serial.write(0x00);
Serial.write(0xFD);
Serial.write(0x03);
Serial.write(0x03);
Serial.write(0x00);
Serial.write(0x00);
...which is a play/pause command, and works perfect.
I'm having problems when the HEX value is 5 digits instead of 4.
For example - here's a HID track forward command.
This presses the key:
Serial.write(0xFD);
Serial.write(0x03);
Serial.write(0x03);
Serial.write(0x100);
Serial.write(0x00);
And this signals the key release:
Serial.write(0xFD);
Serial.write(0x03);
Serial.write(0x03);
Serial.write(0x00);
Serial.write(0x00);
The paired device (galaxy s3 or iphone, tried both) doesn't seem to see the 0x100 command.
According to the BlueSMiRF documentation, this is the format to send a HID raw report:
0xFD 3bytes 0x3 Byte1 Byte 2
And give and example using the following:
0xFD 0x3 0x3
Any idea what to do?

Because it doesn't see 0x100, it sees 0x00, I'm guessing.

OK, how do I get it to see 0x100?

0x100 is outside the range of a byte - 0x00 to 0xFF.

Hmm. Here's the list of Hex codes in the manual:
Any idea how I would send the commands that are outside the byte range? I'm admittedly a newb...
Update - Got it!
Instead of:
Serial.write(0xFD);
Serial.write(0x03);
Serial.write(0x03);
Serial.write(0x100);
Serial.write(0x00);
It ended up being:
Serial.write(0xFD);
Serial.write(0x03);
Serial.write(0x03);
Serial.write(0x00);
Serial.write(0x01);
Thanks to all who replied.
