I uploaded the code and the serial output is attached.

I see. Do I simply upload to the mayfly with the sensor attached? Or is this code to be added in somewhere in my overall code (PlatformIO)?

I am assuming that this is a firmware to be uploaded to the sensor?

I only paid for the one, which was not housed. That one I will keep. The other four they just sent, without first figuring out the problem. If they don’t work I will simply send the four back. Yes, frustrating. Two months of not getting anywhere and now I need to make the decision to figure this out on my own or switch to a different sensor. Maybe something raw that I can house/encapsulate myself.

Much appreciated. There are a few trouble shooting things that I did that may be difficult to explain over the forum. If you would like to discuss my phone is 701-390-2040. These trouble shooting thing did show some interesting results. Any help to get them to work would be great, since I have four ready to go that they sent and I was planning to deploy in the field this November. Been trouble shooting the sensor since August.

Thanks Sara,

I am assuming that the firmware also has something to do with making the sensor signal work over the length of the 3m cable? The sensor does work when attached directing to the I2C port (via. grove cable) on the Mayfly at 3.3v. That’s great, but as you know, I need to run that sensor into the stream.

Honestly my understanding of all this is pretty basic, but I understand that the firmware is very important. I left it up to Northern Widget to upload the appropriate firmware to the sensor before they sent the sensors, so that that process would be streamlined. I did read through their documentation on the firmware and, as you stated before, they have two; I2C and RS485. I am pretty sure the one that is uploaded is the I2C. I am curious to see if the RS485 would work or if there would need to be some revision of the firmware somehow. They didn’t talk about trying different firmware.

Yes maybe someone else has tried this also and can comment.

Thanks Sara,

Thanks Sara,

I have been working with Bobby and Andy Wickert over there on this and they gave me sensors with the appropriate firmware installed already. I did not have to install any firmware. It was just suppose to be hooked up and ready to work. I didn’t know if anyone in the community here was able to get a walrus sensor to work on the MayFly?

Honestly they have been unwilling to work that in depth with me on this and we are currently parting ways on the venture.

That would be awesome, as the ability to re-program and trouble shoot would be beneficial.

Since the boards were not designed to have that capability, do you think it would be impossible to attempt to develop a way to add in a secondary board with a cellular modem that would act as the receiver and uploader for programming remotely? I have come across some Xbee 3 shields which are designed to send and receive cellular data between each other. Do you foresee some major difficulties with attempting to do this. Keep in mind I am new to all this and have minimal experience with open source technology. Just trying to determine the best avenue to take here.

Thanks,
