Questions About SRM

Recently, I bought an SRM Track power meter, I was wondering is there a software that can live streaming my data to my coach's laptop? Is there such a thing? Would like to hear from you guys' opinion! (I emailed to SRM about this question, but they haven't responded yet)

Golden Cheetah can do this if you out an Ant+ single in the computer. The question is the range of your SRM signal. Doubt it would maintain a connection unless your coach is traveling around the track with you.

Yeah, I don't want to say it's not possible now. I'm curious to see if there is a solution out there. But, I don't know of any.

You need a wired track like Carson, or an amped up ANT+ receiver/transmitter to transmit the signal to a receiving station. Range on the SRM itself is pretty small, as are all PM's.

Any idea how Carson's wiring works? Do they have ant+ receivers around the entire track?

Might be an interesting phone app. Ant+ adapter to phone on the rider or bike, to WiFi.

Or an Ant+ to WiFi bridge?

As a guy who has investigated this at a technical level...

- ANT+ isn't strong enough.
- Wifi is odd.
- Bluetooth LE isn't powerful enough and is finicky
- Full-strength Bluetooth (not LE (Low Energy)) might work, but eats a lot of battery power and is still sorta finicky.

There is no easy solution, otherwise you'd see the major manufacturers producing something.

To make the right system, it will have to be built from the ground up, not simply riding the coat tail of another technology.

The limitations are basically the radio transceiver within mobile phones and cycling head units...and whatever device will receive the data in the infield.

The ground-up design starts with using a protocol that isn't ANT+, Bluetooth, or Wifi.. Anything using one of those 3 will be lacking in some way.

Depending on your expertise, knowledge of the protocols and coding skills there would be a way of doing this via a mobile network if you could get a data signal within the velodrome...but yeah it'd be a pretty time consuming affair...makes me wonder if there would be a market for something like this...
