PaulS:
Sending 12 bytes of data 100 times per second is possible. Error detection/correction will require that you send more than 12 bytes at a time. How many more depends on how robust the error detection must be, how reliable the wireless transmitter and receiver are, and how much interference there will be.
Well, 12 bytes per sensor, I'll have to send up to 36 bytes (since I used three), and furthermore I think I need more bytes for instructions such as spaces, CR and NL.
What I am concerned is that if I am going to use spaces, CR and NL (and then get the data sent to Processing and processed), it is possible for my sensors to produce such values as well, and "confuse" Processing...am I right?
I can't see where "wireless" is a necessary condition.
It's supposed to be a wearable device, which will be attached on the foot, and track the acceleration, angular velocity changes, as well as angles of the foot when walking. It'd be very troublesome if it is not wireless.
You might want to rethink this.
Surprisingly, even though it is cheap, it is very reliable, as reviewed by many users and tested by myself.
Thank you so much for your help.
