BigFont eBike (Ant+ LEV and PWR)
· v2026-04 26 V2
About
BLINKING: It is 'normal' at startup for around 10 seconds. seems to be an error of Garmin, not of my implementation!
The bike (Fazua Ride 60) uses to ANT+ interfaces to send data wireless to devices like a Garmin watch or to your Smartphone.
- ANT PWR (Bicycle Power) sending RiderPower [W] , Cadence [Rev] ) etc
- ANT+ LEV (Light Electrical Vehicle) sendig Battery [%], Assist [%] etc
The data for my datafield is sent the following way:
"ANT+ PWR" sendsTo "Garmin API" sendsTo "BF eBike datafield"
"ANT+LEV" sendsTo "BF eBike datafield"
An ANT+ interface can only be conneted to one device!
So in this case:
ANT+PWR must be connected via the "Sensor" menu of Garmin, so that its API (software) can get the values.
Sensor ist shown as "PWR....xx" on the Garmin watch
ANT+ LEV interface must be DISCONNECTED because my eBike datafield connects directly to the Fazua and uses not the internal Garmin API, as it is not available for a datafield.
Sensor ist shown as "eBike....xx" on the Garmin watch
Best is to disable Bluetooth on your Smartphone, start the datafield (by its activity) and then power up your bike.
... and in your activity there should be only one (this) datafield using ANT+ LEV connection!
Please test the DatField before making the payment at https://paypal.me/Seli17/5EUR , then send me the displayed ID from the watch, the type of watch and your country. It is a manual process, but I reply as soon as possible (less than 24 hours). Thank you very much.
ENJOY
Hope you succeed!!
Please feedback!
in addition to my "BigFont MT Bike" App shows:
ANT+ PWR:
- RiderPower [W] as [RidW]
- ANT Cadence [Rev]
ANT+ LEV Sensor:
- Batterie%,
- Assist% (useless on Fazua Firmware 009 (should be corrected with 010) and Spezialized so far)
- Motor Power [MotW] out of Power end LevAssist%. (does not work with Fimware Fazua 009)
= levCurrentAssistLevel% * CurrentRiderPower / (100-levCurrentAssistLevel%)
Default view:
On main picture:
