TuDiabetes - A Community for People Touched by Diabetes

I am a new user of the Paradigm 522. I do a lot of biking. It would be very cool to figure out how the mini link transmitter works. If I had the protocol I could build a windows mobile app that displayed the data in chart and numeric formats on a pda or phone. I can then mount the pda to my handlebars. How cool would that be? Has anybody thought of this? I don't want to buy the real time monitor because they use an ultra low resolution lcd on it and the pump. I assume it is for battery life reasons.

Does anybody have an idea about how to do this? I do not think Medtronic will give me the info. I have 3 electrical engineers at my disposal. :) If they don't give me the info I hope we can reverse engineer the protocol.

It operates on this:

You will probably see something like this come from MM in the next year or so.

Really? That would be cool. I think I would rather roll my own. Part of my job requires analyzing market data so I think I can provide realistic data analysis tools for the sensor data. ALSO: Once I saw the PAL software I thought, "what did they make this in a week?" Pretty amateurish stuff. So I don't know. I do not have an opinion about the CareLink thing yet.

I have no idea about your question, but I would like to know how you set your basals for bike riding.

I haven't started pumping yet. I have been using the glucose sensor for 2 weeks now. I have pump training next Thursday. So far, I have done 20 miles a day for about a week and a half. I have seen a rally in my level during warm up. I have also seen rapid drops during intervals. I am going to ride 50 miles next week so I'm sure I will have further insight. I do know from past experience that high adrenaline rides and rides that include climbing hills can raise my sugar level. I would increase the basal rate I bet. Longer rides I am not sure what what adjustment I would make. Of course, I do not know anything about pumping yet.

Ahhhh thought you were pumping, but you are just sensoring. ;) I have such trouble exercising since pumping and lowering basals for the exercise, just makes me high later. What kind of works for me is 15 carbs every 30 minutes, but I just hate eating all the time.

I do not have the adrenaline issue that makes me go high. Any form of movement and my bgs drops instantly, it is way frustrating. Thought you might have the secret formula. ;)

Karen, this is how I set my basal rates for biking and I am still working on getting it right but it is pretty close. I typically ride 50-100 miles a week, if I am going to go on a 20 mile ride starting at 6pm I do a temp basal @ 25% for 1-1.5 hours starting at 4pm. My reasoning behind this is that basal rates need to be adjusted 2 hours before to show an affect. When I ride it takes me about 1 hour, 12 minutes to ride 21 miles. If I planned on doing a 2 hour ride I would set my temp basal for 2 hours. I still have to eat a little when I am out but for the most part this works pretty well. I constantly look at my pump to see where my BG is and typically it remains stable without any serious drops because of insulin on board.

Hope this helps-Dave

Dave, I've discovered a similar method for running and rollerblading. I use a 50% rate for two hours before I start running, but during the run, I think that i need full basal in order to avoid highs after the run. Glad to hear that you reached a similar conclusion!

Great minds think alike!

That would be really slick if you could pull that off. I am wanting to be able to pull the data off my pump, and i know it will do it over the radio, as thats how it syncs it to carelink. If you move forward on this, please keep us in the loop!

One of my engineers tells me that it will be very to get data from the transmitter without help from the manufacturer. In the mean time, I am going to use a usb sniffer to learn how to communicate with the pump and get the data off of it. Do you have the comlink thing or the usb thing?

I have the Paradigm Link Interface Cable that I connect to my b/g meter. What I want is to be able to do what you say, and send all the data to my phone/pda. (att 8525) I have a fealing that I will need soemthing to be able to pick up the radio signal. My brother is a EE, so I am going to talk to him this weekend about how hard that will be.
