Blynk doesn't send report to my email

Need Help With My Project
1

Hello,
I started using Blynk a week ago. The APP on my iPhone connects through BLE to the nRF52832 successfully. I managed to get the app send me emails containing the authentification token. When I try to use the SuperChart, beautiful data curves were displayed on the mobile screen.

However, when I clicked “Export to CSV”, it told me “sending…” then returned to the project page, but I received nothing in my email.
I also tried to use “Reports” widget. When I click “Run Report”, it told me “sent”. But I still got nothing in my mailbox.

I have used both blynk server and local server, neither worked.

Could anyone tell me what is wrong with my project? Is there any trivial settings that I could have neglected?

Thank you in advance,
Ray

Some Widgets do NOT work on BT/BLE as the device doesn’t actually have a direct connection to the Server. Perhaps these reporting features are in the same category?

3

Thank you for answering, but I don’t get why the reporting widget of the app is influenced by BLE.
Since all the data have been perfectly logged on the iphone, the action needed is only to send data from app to email.

4

Me neither… thus the wording “perhaps” :stuck_out_tongue_winking_eye:

BT/BLE is still in beta, and preferably used with the beta versions of the Apps for full functionality.

If not already running beta App, I recommend you try it and update us.

5

BTW, the data is actually stored on the server, not in the App. Again, unsure if that affects how these email issues work with BT/BLE connected devices due it’s unique link.

The Devs seem to be working on some passthrough connectivity, so perhaps wait for them to chip in… well… after trying the beta App and sending in a Log report, if still failing.

Here are my log files, but it says “no data report for user admin@blynk.cc and reportId 1593074682.”
Could you please have a look maybe something is wrong with my server settings?

Sorry to disturb, but I’m a novice in java server configurations, could you please help me check this?

If this works, then your servers email settings should be fine.
