eCompass and temperature not working #27

amotl · 2023-02-25T08:38:45Z

Hi there,

at GH-12, we were aiming to unlock eCompass readings. However, @UserMacUseface, and @honigwald ¹ both reported that compass- and temperature readings do not work yet with the recent 0.6.0 release. Bummer.

Nevertheless the eCompass (Yaw/Heading, Pitch, Roll) and the Temperature don't provide any readings.

With kind regards,
Andreas.

Together with @UserMacUseface, we are also wondering why it would not work yet. I think I did not use the eCompass yet when conceiving this library, but I am almost sure I received valid readings for temperature and battery level in the past.

May I ask more details about your device? When did you buy it? Which firmware version does it run? Did you upgrade the firmware once already, or is it a vanilla device? Does it work when using the accompanying smartphone app?

P.S.: Same questions to you, @UserMacUseface. Thank you already!

Can I ask you both to invoke the program with the --debug option? Then, you should see corresponding debug output from the decode_reading() method, effectively Received buffer: and Decoded reading:. It probably will not lead anywhere, nevertheless I wanted to tell you about it.

I bought my Calypso (the one you can see in picture of the README file here) recently.
Here are the information's from Calypso App:

Manufacturer Name: CALYPSO
Model Number: POR
Hardware Version: 3.0
Firmware Version: 2.18
Software Version: 1.41C   # Added from debug output

I didn't executed a FW-Upgrade yet.

Will check the outcome later, since I've to leave it for today as it is but I attached the debug logs. :)

Thank you very much. It may make sense to add the --compass=on option as well to the read command, like

calypso-anemometer --debug read --compass=on

Sorry for missing this.

info

From the info debug output, I can see the eCompass should be turned on. The response bytes for (mode, rate, compass) status are (\x02, \x01, \x01), translating to (CalypsoDeviceMode.NORMAL, CalypsoDeviceDataRate.HZ_1, CalypsoDeviceCompassStatus.ON).

Those lines within the explore output also indicate that the eCompass is turned on.

Within the read output, those are the relevant lines where the actual reading at 00002a39-0000-1000-8000-00805f9b34fb is requested.

Just to make sure: We do not see a regression here, do we? So, version 0.5.1 displays the same output? It can be installed using pip install calypso-anemometer==0.5.1.

^^ Edit: Probably not relevant, as the reading seem to be conducted properly, but \x00\x00\x00\x00\nd\x00\x00\x00\x00 clearly indicates that there is "not much to see here".

amotl · 2023-02-25T10:20:55Z

Better question:

Does it actually work, and yield valid readings, when using the accompanying smartphone app?

amotl · 2023-02-25T10:48:40Z

For custom BLE conversations and explorations, I found the nRF Connect for Mobile application (latest apk) very comprehensive and useful when investigating some BLE GATT ESS characteristics the other day ¹. It may also help in this case, in order to have a third BLE client application around, to be able to compare between each other.

Recap:

characteristic uuid	name	description
0000a003-0000-1000-8000-00805f9b34fb	Activate clinometer and eCompass	0x00 or 0x01, whether the compass is enabled or not.
00002a39-0000-1000-8000-00805f9b34fb	Heart Rate Control Point	The actual reading, a 10 bytes response, decoded with `CalypsoReading.from_buffer()`.

The application is also displayed within the Calypso Ultrasonic developer manual.

Hi again. GH-28 has some important information about the compass, its intention, and quality. On the matter here, the FAQ has a few interesting items:

Q: I am going to install my device, is it necessary to recalibrate it?

A: Yes. You need to calibrate your compass depending on your geographical area to compensate
magnetic declination and depending and on the magnetic nature of your boat to compensate
magnetic deviation.

Q: I calibrate the compass but it doesn't work fine.

A: Repeat compass calibration turning the device slower, to minimize deviation. Still, this is a secondary sensor and it will not deliver the features of a professional dedicated compass.

UserMacUseface · 2023-02-25T13:23:31Z

In the current version of the Calypso "Anemotracker" app, I get -... for pitch and roll and 000 for Heading:
In this version there is also no way to see the devices temperature reading.

There is a button for calibration in the app settings, but pressing it yields an error message telling me I should enable the clinometer first. Unfortunately there is no button for this.

Once more,

on the quest for the eCompass

#27 (comment) says:

[The compass] is a secondary sensor and it will not deliver the features of a professional dedicated compass.

Combined with what we learned here and at GH-28, I'd say it's clear that even though Calypso used to clearly state in the earlier documentation what expectations you can have about this sensor, they now stopped promoting the sensor at all. Of course, I then wonder why they still have the values displayed in their app at all.

amotl · 2023-02-25T13:39:59Z

There is a button for calibration in the app settings, but pressing it yields an error message telling me I should enable the clinometer first. Unfortunately there is no button for this.

Apparently, there has been corresponding machinery in an earlier version?

[1] also has excellent information about this topic.

PLEASE NOTE: THESE INSTRUCTIONS ARE FOR THE OLDER GENERATION CALYPSO ULTRASONIC THAT CONTAINS A COMPASS. THE INSTRUCTIONS ARE SPECIFIC TO MARKSETBOT USERS AND SHOULD NOT BE USED BY ANYONE ELSE (THEY WILL DAMAGE THE LATEST HARDWARE).

If you bought a Calypso Ultra to use with your MarkSetBot, it is essential that you upgrade the firmware and calibrate/swing the Calypso Ultra wind instrument's compass. Both tasks are fairly technical.

The compass must be calibrated before it will work well. The Anemotracker app has a compass calibration/swing feature. For calibration to work correctly, the Refresh rate needs to be set to 1Hz from 4Hz during calibration. We are hoping that Calypso will build that in to their app automatically in the future.

It is critical that you calibrate in an area that does not have magnetic interference. This is more difficult than you would think. It is recommended that you take a hand bearing compass and walk around a space to make sure it reports correctly. We have found many docks and hoist areas at clubs have so much interference that they will report 90 degrees wrong with a hand bearing compass.

Tried to calibrate the compass using the nRF connect mobile application to no avail.
Maybe these sensors have been disabled.
I will see if Calypso can confirm that.

honigwald · 2023-02-26T18:38:31Z

Hi! Sorry that it took me some time to test/reply.
I tried nRF App with two Calypsos (Mini, Portable) and at booth devices I can't activate, calibrate or read compass values.
Maybe Calypso removed the eCompass due to semiconductor bootle neck xD...

On the other hand, I was able to gather information about the battery level, so no clue why we're not able to collect this data through the py-libary, too. Or did I miss something?

UserMacUseface · 2023-02-26T19:18:32Z

Well. Battery is non problem. It seems however that nRF can access the battery level via an undocumented service which displays the level with two digits instead of one.

Do you get a temperature reading other then 64?

amotl · 2023-02-26T19:27:32Z

eCompass

Thank you also for reporting back. I think we can cancel our quest for the eCompass, right. @UserMacUseface is trying to get some more feedback from Calypso about it.

Battery level

Observation

On the "battery level" reading, @UserMacUseface also found that the device responds with zero (0x00) within the response when reading the "Heart Rate Control Point" characteristic 00002a39-0000-1000-8000-00805f9b34fb.

Investigations

On the other hand, he discovered that the device may use the generic Battery Level characteristic GENERIC_GATT_DEVICE_BATTERY_LEVEL_UUID (00002a19-0000-1000-8000-00805f9b34fb) from the Battery Service 0000180f-0000-1000-8000-00805f9b34fb instead.

Maybe the newer firmware releases are encoding the data differently. Using a standard characteristic is a good thing in general, but we will need to adjust the driver.

Details

This is the corresponding part of the explore log of your devices:

Sadly not. I also got only 0x64 as temprature value back and it won't change not matter what I do.
Today I contacted calypso as well to see if this is FW related and if there is coming a new release in the future which will suppport Temp and Compass.

amotl · 2023-02-28T17:43:10Z

Hi again,

The newer device generations seem to implement emitting data on generic BLE characteristics and services. For example, the Battery Level characteristic GENERIC_GATT_DEVICE_BATTERY_LEVEL_UUID (00002a19-0000-1000-8000-00805f9b34fb) from the Battery Service 0000180f-0000-1000-8000-00805f9b34fb seems to be used.

In the same spirit, your devices now seem to use the generic Environmental Sensing Service 0000181a-0000-1000-8000-00805f9b34fb for emitting wind data on those characteristics, see GATT » Environmental » Wind UUIDs:

Apparent Wind Speed 00002a72-0000-1000-8000-00805f9b34fb
Apparent Wind Direction 00002a73-0000-1000-8000-00805f9b34fb

Using a standard characteristic is a good thing in general, but we will need to adjust the driver.

With kind regards,
Andreas.

Hi again,

we have a few news. Calypso is now designating the Developer manual 1.0, called CALYPSO ULTRASONIC Portable Solar & Mini Developer Manual, as the official one. Also, we received those statements:

Battery level is still legacy service with wind direction and battery service 1-9. The new ones are Environmental service and Battery Level which control Wind direction, speed, and battery levery are from 0-100.

The difference between hardware 2.5 or 3.0 is just changes for internal purposes in the manufacturing department and there is nothing different for the customer or in how it will work.

As for secondary sensors, the units used to have secondary sensors a couple of generations ago, but the models nowadays do not have secondary sensors. Information like location and temperature is acquired from the internet. The wind reading will not be affected by heel or roll and has a damping in place for pitch. The wind sensors give wind direction and wind speed.

With kind regards,
Andreas.

Thanks again, @amotl!

Calypso didn’t respond to my mail request until now. I’m a little bit sad that they removed? eCompass, but good to know that they changed to another official dev guide.

honigwald · 2023-03-14T11:33:42Z

Hi all,
bad news from Calypso support.

Received on 09.03.2023:

Hi Simon,

Thank you for writing to us! Actually our devices don't have eCompass anymore. I have attached our latest version of the Developer's manual for your records.

Let me know if you need anything!

Best regards,

Rebekah

Looks like there is no chance to activate something, which is not present anymore...very sad, that they removed the hardware without notice.
