Easier path to start with

[Paolo Cecchini]

Hi.

I have Ant+ successfully running on Raspberry Python for years now. I did that to interface with my C2 rower. I would be happy to try on microcontrollers now, better if within the Arduino IDE.

What is, if any, the easier path to approach? As an example, I own this

radio

but it looks like mostly useless because of interfacing issues.

TyL for any hint. Cu. Paolo.

Hello Paolo,

The easiest approach in my opinion is to get a D52 module dev module from dynastream and hook it up to a 3.3V controller using UART. It comes preloaded with the correct radio stack which is where a lot of pain of getting it setup is if you pick another board. The wiki has the recommended wiring. Let me know if you have any other questions.

Hello Paolo,

The easiest approach in my opinion is to get a D52 module dev module from dynastream

I'm going to order the board, TYL.

 

and hook it up to a 3.3V controller using UART.

Esp32 hopefully.

Goal is to read the Ant+ stuff and send to a MQTT server  for further processing. The all-in-one approach with Rasp & Python works but is a little tricky and subject to no RT OS.

TY again. Paolo.

Hi.

I received the D52 dev module yesterday.

Short version. I succeeded with both the example sketch Callbacks & HeartRateMonitor.

Long version.
Wiring to esp32:
        3v3 to J101.01
        ground to J101.02
        d17 to J101.03
        d16 to J101.04
        ground to J101.17, J101.18, J101.19, J101.20

So we've baud rate 4800 on esp32's Serial2.
And, of course, I supplied the required network key.

I'm planning to go further with the raw data approach to verify the FE-C interfacing.
Meanwhile, if I'm not wrong,  I noticed the FE-C profile(s) are not yet available on the Antplus library.

When and if I'll be confident about it, I suppose the best approach is to fork the project and open a pull request. So more later :)

Paolo.

Post Scriptum. When you write to connect to 3.3V rail to set the baud rate, I guess you mean digitalWrite, otherwise must be a kind of current limiting hardware on the D52 ... but maybe there is, and I missed it.

[Paolo Cecchini]

Ok, the brute force approach is going to work ...

Just an FYI Charles reached out to me recently to work on FE-C as well. I think he has a public fork but I don't know if he pushed anything. Maybe you two could benefit from each others work.

Hi Curtis,

I almost finished mine !

I juste need to clean the code for a merge request

I'll provide a native driver example.

May be today or tomorrow

Excellent. Ty. Paolo

Btw, any rower, Concept 2 actually?

Looks like rower is part of the pull request https://github.com/cujomalainey/antplus-arduino/pull/31/commits/4a3c4b3c43cf7743bae6f51dc08de6e02b0e588e

Will do a review once PR is updated, thanks Charles.

Hi Paolo,

I have finished merging the code from Charles, I recommend you rebase any changes you have on top. Thanks

I will, Ty.

Meanwhile I'm having fun with that board and openocd :)
