I installed the Seeed Xiao and the antplus library on the arduino IDE as described in following link: Getting Started with Seeed Studio XIAO nRF52840 (Sense) - Seeed Wiki
Now I can upload example projects from seeeduino to the board and I can compile examples from the antplus library on other boards.
Whenever I try to compile an example from the antplus library on the seeeduino board, I get following errors:
When I look in the header files of the seeeduino board, I noticed indeed that the Serial was defined as UART1:
It seems that the antplus library can not handle this, and does not recognize UART1 as a type?
Can the Garmin take BLE data instead? I have never used the Arduino libraries but I have a lot of experience using ANT+ in group fitness applications. While ANT+ works great when you're on the receiving end, it's a pain in the ass when it comes to reliably transmitting data to a sensor.
If BLE is available, that will probably be much easier.
Thank you for your answer!
I think using BLE should be possible, but I would prefer to use ANT+.
I am trying to make a powermeter and ANT+ would allows to make a dual sided powermeter, while that is harder with BLE.
Also, the "antplus-arduino" library already contains a powermeter example, so (I think) they already took care of the transmitting message protocol of a powermeter.
Hi, thank you for your answer!
Indeed the error message comes from the file "libraries/ANT-Arduino/src/MainClasses/ANT_MbedSerialAnt.h", but indirectly, that files calls a function that uses "Serial1".
This file is contained in thee "ant-arduino" library: ant-arduino/src/MainClasses at master · cujomalainey/ant-arduino · GitHub
My apologies, I forgot to mention this library, it is installed together with the "antplus-arduino" library in the arduino ide.
Yes, PWR (Bike Power) is standard ANT+ profile.
Maybe I misunderstood. I thought you were trying to send directed ANT traffic to the Garmin specifically. If you're "just" broadcasting PWR messages, that is far easier.
