    Hello,

    In thoses  cases do you have another device in operation nearby, which is able to manage the ANT+  or BT connections?

    Like a Smart Phone or an E-MTB, or ?

    If the answer is yes, get yourself into conditions to reproduce this defect without the presence of this "intruder".

    cordially

    Hi Eagle

    Thanks for your reply. I have had my phone with me, but BT is always off to save its battery. I will try again with my phone off. 

    I cannot remove the E-MTB from the situation because that is the exercise that I am doing when monitoring my heart rate. There is no option to turn off the ANT or BLT on the bike. Surely it should work with both HR and bike present anyway?

    I will try just the bike connected on its own and see if that stays connected because I can turn off my HR sensor.

    Do you know any reason for the 2-hour limit on the beacon transmitter?

    Many thanks

    Wayne :-)

    Hi Eagle

    I have tried various different things to try to diagnose or resolve the problem.

    I had the HR monitor connected to the GPS successfully for several hours with the GPS resting at home, which confirmed that it isn't a 'time' related problem. It was also connected to my phone and was happy to display data on both devices simultaneously without fault.

    I tried having it connected to my e-bike on its own, without the HR sensor, and the ANT connection failed after not very long, so it appears to be the GPS side of the communication that is failing, rather than the HR sensor side.

    I went for a ride today on an analogue bike without my phone or any other BT or ANT devices anywhere near and the connection to the HR sensor failed after a while, maybe an hour or so.

    After these tests it appears to me that the disconnection occurs when the device is subjected to vibrations encountered when on the bike.

    Would it be helpful to download the logs from the GPS?

    Cheers

    Good evening,

    yes of course make a status report and open it with a text editor.

    It is also important to place the GPS on a cushioned support, to preserve it from the vibratory environment and shocks.

    cordially

    Hi, Thanks for your reply.

    It is mounted on the bike mount supplied with the nav, is that not good enough?

    Thanks

    It is quite easy to read and follow what the GPS did by reading the .log files. For assembly, the effect of vibrations and shock transmitted by the vehicle to the components is incidental, which favors the appearance of breakdowns without it being possible to establish the link with the cause.

    There are many files in the extracted log file.

    I have looked at some of them and in 'AT.log' (which appears to be GPRS data) there are some  occasions where [ERROR] is shown a few times in the column otherwise showing [INFO].

    I did a long ride on the 6th of Jan, starting out at 10:39:16 and there are a few occasions when it shows [ERROR] at the start of a new position transmission (which occurs every five minutes). However, after two hours and 10 minutes, starting at 12:49:20 it shows [ERROR] for the next eight hours.

     

    Where can I buy the cushioned mount that you show above? Will by 'bike' GPS fit in the cradle with the 'butterfly' on the back case do you know?

    Cheers

    The most important file is compegps.log

    You can  buy the cushioned mount  here

    Support

    Accessoirs  

    Quick Lock

    Fix the quick lock cleanly on the cushioned support with two screws

    Di you have errors in others log files ?.

    I have no errors in the AT Log file of my gps. Submit a request to support, via the link at the top of this page for a repair. Your Blur Tooth antenna may be disconnected. With CROSS the GPRS uses your SmartPhone. For other GPS it's 2G. cordially
