Hi, I'm currently following this project and have all the scripts running fine on a small odroid running ubuntu. The scripts run fine but I'm not getting any data. This is possibly because the Next Link 2.4 dongle does have a driver. Can you confirm your setup and if you are using any specific driver to run the dongle. It shows up on lsusb but I get nothing via pcap Thanks again Nik

Hi Nik,

I'm running on OS X without any drivers. The USB stick itself is a HID device, so as long as you have pip installed all the dependencies, it should work. I've also run it on Windows, though I must admit I haven't tried Linux yet. Have you updated the hard-coded variables at the top of the MedtronicSession class? The first part of the MAC's are your pump and stick (link) serial numbers. Leave the numbers after the + the same. Use the get_hmac_and_key.py script to find out your HMAC and key.

Hi Lennart, Right, yep I did the Hmac and Key, that was fine. I noticed the MAC address before the + sign and I have changed them to suit both the link and pump. I get the Link device info then a send and receive data but then it starts going through the channels (send/receive). So that's where I'm up to. After it does the channels it just crashes with a couple of errors. The Link is setup on the pump. I'll get some data over to you but it all seems to be going well. Nothing seems to be going into the sqlite DB I'm running it on an Odroid with Ubuntu and python 2.7 Pythons not my cup of tea, I'm more of a C#/PHP, I may get my son on the job. Cheers, Nik

It looks like you’re using the wrong key and HMAC for your stick serial number. I’ll be pushing an update later in the week to make this a lot easier (it will read the serial number from your stick and get the key and HMAC for you, saving it to the SQLite database).

Maybe it's down to how close the pump is to the dongle. The pump is located on my son and the dongle is plugged into the odroid but not always in proximity. At the moment he is sat 3 meters away and here is the result, not errors:

Sensor BGL: 773 mg/dL (42.9 mmol/L) at Mon, 02 May 2016 16:43:57 +0000 The sensor has expired 'change sensor' so we will need to restart the sensor to start getting figures.

@niksimms, I've opened #5 and #6 to cover the items you're talking about above. I've split them out, because they're 2 different problems, making them easier to track. I'll close this issue since I believe we've resolved the initial reason for this particular issue.
