Distance Measurement between motes using RSSI measurements
« on: October 16, 2015, 11:20:38 PM »
Am interested to enlist some help to progress a new project. I have two issues: getting Moteino Mega's working on my laptop, and writing code to get Moteino's to measure RSSI when polling each other at regular intervals, then working this back to distance between motes. Am based in Sydney Australia.
I purchased Moteino Mega boards, power shields and batteries, but can't program them on my laptop. Seems there isn't a valid com port. Purchased Arduino Uno to see if they work, plugged it in and worked straight away on a valid com port! Would prefer to get Moteino working due to capabilities and size. Hence some assistance to get them working would be greatly appreciated.
Also, would like to enlist a programmer to do some code work. Need someone to write code to poll any motes within 10 metres only, on 415mHz, at set time periods,returning timestamp, IDs and signal strength. Then convert the RSSI to a distance between Moteino's. Have done this previously with SunSPOTs but prefer to work with Moteino. This project will then expand into other areas from here once testing is successful. Happy to pay for work done. Again, based in Sydney Australia.

paulM,
MoteinoMEGAs require a FTDI adapter that does the job of creating a serial port for you. You haven't given any details how you're doing that part. ArduinoUNOs have the same mechanism, except everything is on the same board.
I think there were some others that wanted to do distance measurements based on RSSI but that is not going to be an exact science since the reception is influenced by so many variable factors. You would need a very controlled environment to get any kind of predictable results, at least that's my impression.
