Always a flat trend arrow in Nightscout upload

[gpgerrard]

Using Xdrip (13 June nightly) getting readings from CamAPS FX. Xdrip shows the correct trend arrow but the MongoDB entries show that the upload is always 'Flat' regardless of the delta. Three consecutive readings below showing steep falls (and downward trend arrow in Xdrip) but all with 'Flat' direction in the upload.

Thanks to all the devs for adding CamAPS support by the way - it's been a game changer for us and no longer have to have a second phone collecting readings in the pump slot so we can follow our 3yo daughter more easily!

xDrip always calculates the trend arrow using the current and the previous reading.
But, other apps may take more than those two readings into account for calculating the trend.

This results in discrepancies. It's not necessarily an issue.

These are examples:
#414
#691
#800
#920

Do you also upload to Nightscout at the same time? It is quite interesting that the doMongoUpload function does not upload the delta value but it is shown in your records above. Where do you get these records from?

[Navid200]

What does it show in the data table?

Whereabouts is that in the app? Have had a look but can't find it! Thanks

No arrow at all in the data table

I think I can resolve this with some work but I'll need to work closely with a camaps user like OP over multiple iterations. If you're interested to work it out, please can you email me at jamorham at gmail

Will do, happy to help! Thanks again.
