Project to enable Bosch + Garmin integration

[Shark58]

I wonder if the data via bluetooth can be reverse engineered.

No need, it's a new open data interface from Bosch. No license, no registration, no fees.

That spec gives less data than is already sent from the smart system to the flow app. No motor power, no assistance mode and loads of stuff that's not relevant to MTBers.

Tested it the last weekend with my 1040. Works quite well, except the "auto stop" function. I got up to 7km/h speed data even if I'm resting and the bike was laying on the ground.

But I'm okay with it for now and will keep using my ant+ sensore for it.

Power works, battery consumption/state as well. Love it. That's all I wanted.

La batteria dovrebbe segnalarla, l'unica cosa che non segna è l'assistenza.

You are correct, it does show the battery

Hi all,
i've integrated the new Bosch protocol with and esp32 (as a gateway) to my Suunto watch. I needed the ESP32 because Suunto can only act as a Master in the communication and unluckily Bosch is also a master. I'm pretty sure it can be easily done also on a Garmin via Monkey C.
Don't have a lot of time to follow the project but i've make it open source so you can all take a look if needed.

Very nice. I’m kinda doing the same thing to be able to connect a Garmin Edge 530, which isn’t supported by Garmin beta update.

For development I’m using an M5 stack stick. But will use something with an esp32 when the software works good enough.

 

[HexagonSun]

I've just published a new release of my code which will now transmit both ANT+ and BLE power sensors so you can choose which one to use on your GPS. I've found that my Garmin 830 has a fairly fragile Bluetooth stack and running with the phone connected and the Bluetooth power sensor caused some issues. The 830 has a dedicated ANT+ chip and I've had no issues at all when using it with the ANT+ sensor.

I've tried to document the new board build process as clearly as possible, but I didn't do a clean install from scratch so may have missed a couple of details. Please let me know (here or Github) if anything needs updating. I've also focused this build solely on the Seeed XIAO nRF52840 Sense board as there's a bit more config work to set the board up in the new environment and I don't have an Adafruit board to test it with.

Next steps will most likely be looking at adding the LEV (ebike) ANT+ profile alongside the power sensor which will enable a bit more data to be displayed. Might also look at an option to grab power, cadence and battery from the new Garmin BLE profile which could allow you to just use the board rather than needing the phone as well.

Oh and if anyone is using it I'd love to know the configuration of motor, phone, board and GPS so I can update my 'known working' list.

Thanks, when I am next able to I will give it a go with my 520

[PROJECT] Bosch eBike live data on Suunto Race S — open source ESP32 bridge + SuuntoPlus app

Hi everyone, I ride a Bosch eBike and I wanted a single place for all my training data: GPS, heart rate, and also what the bike is doing — cadence, motor pow...

forum.suunto.com

Quick update to share some updates I made to my personal project:
I’ve added a new branch in the ESP32 repo:
GitHub - SellA/BoschEBikeESP32 at feature/multi-mode

Besides the standard bridge mode, it now supports exposing standard BLE sensor profiles as well:

• Power + Cadence
• Speed + Cadence
• Power only

These modes don’t provide the full Bosch telemetry, but they work without the companion SuuntoPlus app and integrate natively with Suunto’s internal metrics and training features. For example, power data is correctly used for Suunto power zones, training load calculations, and related analytics. Should be working with all other devices that support standard BLE sensor so Garmin watches and bike computers.

I also updated the integrated WiFi access point UI, where all bridge settings can now be configured directly from the browser:

There is now also a simulation mode that allows testing the connection with watches and bike computers without needing to connect to the actual eBike. Useful for validating the setup or experimenting with different configurations without having the bike nearby.

With which hardware-software combination?

Hardware, is the 400wh battery and mini controller and top tube LED display. The software in the Garmin was the Beta version,

 

[rfgamaral]

Has anyone been able to connect a Garmin watch (which watch?) to a Bosch eBike with the latest software updates?

 

[HexagonSun]

I think the official Bosch-Garmin connection only supports some specific Edge models at the moment, maybe they'll add more support in time. FWIW my wife's Venu 4 finds the sensors that my SmartBridge solution generates.

Hi @HexagonSun,
I have startet to prepare the switch to ANT+, but I am kind of stuck... In your tutorial you write

Link your ANT account to your Github account to gain access to the ANT libraries. Select Apply for Evaluation License at the bottom of My ANT+ - THIS IS ANT

How is this supposed to be done? I have successfully transformed my user to Adopter, but I can't find any option to continue as described...

Try this link - looks like I posted the wrong one in the README - please let me know how it goes

ANT for nRF Connect SDK - THIS IS ANT

ANT is a Wireless Personal Network protocol, by Garmin Canada, with small size, reasonable cost and very low power requirements.

I successfully migrated to the ANT+ version and tested on a 40min ride without any issues, everything worked flawlessly! Thanks a lot for your great work @HexagonSun

Hi @HexagonSun

EDIT - self correction - I was stuck on Step 9 of your Readme on the SmartBridge Firmware update
"9. In the nRF Connect extension WELCOME panel select Open an existing application and open the "SmartBridge_Zephyr" folder from your cloned repository."

I had downloaded a zip file from the latest Github page but had unzipped the file and a location that Visual Studio Code couldn't read. Once I moved the folder to my main "user folder" in MacOS - it could read the folder path.

I completed the rest of the build and now have Ant+ power connected via my phone. Off to test on the bike now.

My hardware is:
Phone = Android Nothing Phone 3
Motor = Bosch Performance Line CX Drive Unit
Garmin = Epix 2 Pro Watch

@HexagonSun - I would be very interested in getting the LEV profile working and/or otherwise getting eBike Battery power showing on Garmin. My eBike Controller only shows 5x bars (in two colours) so it would be great to see the actual % without getting phone out (and I'm not always catching the notification pings to my phone on the 5%/10% drops). If you could get the SmartBridge to connect straight to the Bosch Controller - that would be great and remove one extra step of the phone.

But thanks again for all of the development work - it is great!

 

[HexagonSun]

it would be great to see the actual % without getting phone out

Coming soon!

Have you already bought hardware? If not then maybe try @Theray2189 solution for ESP32 - that doesn't need an Android Phone app to act as a bridge. It does seem to be all Bluetooth though? No ANT+?

Any chance for iOS working solution?

All the code is public on Github but there's some Android specific Kotlin at the moment. If anyone can translate the Android specific Kotlin bits so they work on Kotlin Multiplatform/IOS then it's possible but I think Apple will only retain an unofficial app for 7 days before it needs to be verified again so that's more of an overhead.

Once I've got ANT+ LEV fully working I'll take a look at using the new Garmin live data interface but that's missing some of the data fields that are currently grabbed from the Flow app data feed so functionality would be reduced, but it wouldn't need the phone in use. The seeed nrf52840 board doesn't support wifi so expect the app would still be needed to configure things before use, though as that'd be set up over BLE it could be do-able via nRF Connect.

Anyhow got a few wrinkles to get out of the LEV profile first - I'm running into the same issue that Bulcan users had where speed isn't zeroing and forcing it to zero can have "unintended consequences". Maybe the LDI protocol handles that better!

 

[HexagonSun]

A request to anyone using SmartBridge - as part of the LEV development I'm trying to isolate battery capacity from the data but can't be 100% sure with only the data from my bike, Could you grab a log or two from your bike during your next ride using the 'Start Logging' button in the app and share it either here or on the github feedback discussion topic (Feedback · Nilogax SmartBridge · Discussion #2). Also please let me know what your battery capacity is. Ideally someone with a battery other than 400 Wh and/or someone with a Powermore to see if that's listed separately.

Thanks!
