Hi,

I have been testing both the sidddy / Flora and Lociii / Flora but I runt into issues.
With the Lociii fork I get this after it connects to the flora:

  • Failed to find data service

Anyone that got a clue on what to do?

Thanks

I have the same issue. Any ideas how to fix it?

Please check the following:

  • did you enter the correct MAC address for the device?
  • is the device in close distance to the esp32? At least for testing purposes, you should have the sensor max 1m away from the esp32. Once the connection is known to work, you can test how far away you can position the sensor.

If this does not help, please provide the serial log of your failed connection attempt. Note that the changes from Locii were merged now, so please pull the master branch for your tests.

That's weird, it looks like the connection to the device itself is successful, but the device does not offer the required data service for the connection. Could you check with some bluetooth analysis device if your flora sensor actually provides the data service with UUID 00001204-0000-1000-8000-00805f9b34fb? Easiest way is probably to use an app on your mobile phone to check this, e.g. nRF Connect.

ok... let me have a look how we can debug this further. I'll get back to you later this week.

Hi,

could you try the following?

  1. Please flash flora with "Core Debug Level" set to "Verbose":
    image
  2. Check the content from Serial Monitor after reset. You should see lots of log entries from ESP32 core now. We're looking for entries with content "GATT Event: ...". If you see these, debug log was successfully enabled :-)
  3. Please attach the complete content of the serial monitor here.

BR,
Sidddy

Got the same problem, but sometimes it works, after I reset for a couple of times. It also doesn't work reliable when the flower sensor is right next to the esp32. Any tips, would be very helpful :-)

Hi siddy - yes it does still occur with the latest v1 esp32 board - I have the same issue.

connection to device successful - failed to find data service

When I inspect the sensor with lightblue ble scan app on android it works fine and I can
read the temperature value by selecting the data service uuid and characteristic uuid.
Those uuids are identical to the one defined in config.h.

I have quite a few of the flower mate sensors 2016 version and so far they all fail in the same way
but somehow this lightblue app is perfectly communicating with them through the same uuids - strange.

Also tried it on a raspi with golang and it works.

I think I discovered why the data service is not found. I added this line Serial.println(serviceUUID.toString().c_str()); to the program. It prints the UUID and as you can see the UUID is missing 2 characters (fb) in the end, but I don't know how to fix it.

If I pass it defined like so:
const char* serviceUUID = "00001204-0000-1000-8000-00805f9b34fb"
to getService the serial println shows the correct string.
However, the lib still fails to find the data service as it is cast to this BLEUUID object.
I suspect that the error occurs in this library here.

Thank you @e6on and @ng2dev for your analysis. Now it works for me :-)
In Arduino IDE I searched for ESP32 BLE and added the library by Neil Kolban / Version 1.0.1 - which is also stated at the main page of his project.
Sketch -> Include Library -> Manage Libraries...

Instead of this:
#include "BLEDevice.h"
I now added that library:
#include <BLEDevice.h>

Now I can see the sensor outputs.

I have a Miflora plant sensor working with well with ESP32 using this s/w.
I just took delivery of 5 VegTrug sensors.
They connect to okay, but the program cannot find the data service.
I am in a position to do any testing necessary
