Source for CPE.bin data file...

Does anyone know where CPE files can be downloaded?

Background - I've written a tool which runs in the systray of my notebook and waits until one of my watches will be connected for charging. As soon a Garmin watch is recognized, a backup of all new activities is done and the EPO file gets updated (for devices like the Forerunner 935), so no other programs (Garmin Connect, Express, etc. is needed). Newer generations of watches do need a CPE.bin file instead of the EPO.bin file - so that's the point why I ask.

Any hints? Wink

    Didn't know Garmin does read this forum Wink

    If so, they would do a better support for their customers - two months ago I asked the support how Garmin will deal with firmware bugs of the Forerunner 955 - I wrote exact descriptions for three issues and made screen shots what's going on. First I got a mail what should be done to solve some things (with totally useless information), later I was told that all the behaviour is normal and simply  there does not exist a bug - the support just mocks customers.

    Actually I am in contact with the consumer service of the european union and we think about initiating a nice process to get a better support.

    Have you tried asking in the forum about what you consider to be bugs? Maybe they are not bugs.

    If you are a coder, it should not be too difficult to get the location using a network monitoring tool, and watching where it is being downloaded from by Garmin Express.

    Yep, but I'm not sure if this is what Garmin wants Slight smile

    Meanwhile the non-bugs are in a bug list in the forum, but this list entries only represents the customers view not the perspective of Garmin.

    Sounds like a lazy excuse Stuck out tongue winking eye

    Maybe for you, but iI had sone experiences - I've reported severe software bugs some years ago to Garmin for instance: first they where sceptical, than cooperative (including fixing some of the coding errors) but later on code investigations where not accepted.

    So breaking a https session is one thing, replicating the Garmin Express behaviour another - but making a tool public which is downloading the CPE file like this?

    Since garmin doesn't pre-compile/download EPO.BIN but actually builds it from raw data, it's possible CPE.BIN is also built this way and not pre-made?

    Search the web for "omt.garmin.com/Rce/ProtobufApi/EphemerisService/GetEphemerisData" and you'll see how they do it for EPO.BIN

    I haven't seen the format for CPE.bin but it's used on many Sony chipsets so must be documented somewhere.

    Alternately it is possible to "snoop" on https connections on your own computer using various tools like "Fiddler"
