@braedon-dority it seems to me you have “bridged” or wirelessly connected one S3B/Mayfly1 to another S3B(XCTU or Mayfly2) and proved the data connection.

A vehicle represents a number of parts  that hang together ~ ModularSensors represents a number of Classes that hang together – the value of open source is you can now connect them…[Read more]

@braedon-dority I would add that the Digi range of modems is extensive- with many functions. They have good “Data Sheets” on their capabilities.

What it sounds like you are asking is can two S3Bs be setup like a “wire” – a link for two S3Bs – a peer-two-peer (P2P) link.
That is “print”  an ASCII serial string to an S3B over the UART and have it…[Read more]

Thanks for the explanation – I do so appreciate that the code at 9600 baud works, and there is a lot of hard work gone into configuring it  – as you say to work both first off and subsequent power ups.

Coming from a  real time programming background I keep forgetting about the simplicity of Arduino. So I keep tripping over  issues like this – it…[Read more]

Thanks for the update with cct – (at least sorry if I didn’t see it the first pass).
Thanks for the reference to the sketch. I tried running the sketch, and I just couldn’t get it to compile – 3hrs trying – sometime I just admit defeat and move on. So I used it as an example with another sketch that I have running and got it working.

So super…[Read more]

Hello Dan, thanks for the info. I’m using RevX from Digikey “,”1998-251-ND”,”VERIZON SIM TRIPLE FF CAT-M” with XB3-CA-2/XB3M1

For the Enviro LTE Bee, RevX supports suggests ATT may be more flexible, so fairly low rish ~ 1998-1011-ND RevX Systems Corp. TRI SIM 2FF/3FF/4FF SIM AT&T
I’ve got a query out to Digikey about an M5Stack Variant of the…[Read more]

I think I found the answer by emailing support@rexV, since I got it from amazon.com Mar.2022 it wasn’t certified for Verizon.

This can be checked https://opendevelopment.verizonwireless.com/activation-troubleshooting

support@RexV said “RevX does not certify devices for use on M2M/IoT rate plans, rather the manufacturer registers the IMEI with…[Read more]

Hello @mbarney,  or @dan-wachusett  I’m looking to try the LTE BEE – just wondering if you have used the RevX Verizon CAT-M sims.

I have been using it with the Dig XB3-C-A2 and have a few spare. Seems like it should work at this stage, but many ships have foundered on unseen shoals.!

There is some onchip references, but maybe not useful. From the manual mega164A_PA-324A_PA-644A_PA-1284_P_Data-Sheet-40002070B.pdf   (applies to the mega1284)

Hey thanks for the overview. Welcome to the art of jumping in – and learning by doing (my philosophy though I’m an EE graduate) – though its beneficial to bring an engineering basis to analyzing the components, and then plug the components together.  The engineering basis can be thought of as a technical story – though for EE graduates we talk…[Read more]

Gosh Brandon, I successfully used the 900Mhz modules about 15years ago with the TinyOS framework.

Seems you are thinking of using it in a Peer-2-peer arrangement, possibly in a mesh configuration. A lot of options.

I wonder what your back ground is  – cause its sort of like jumping into the deep end, and you may wanna flesh out your plan – what…[Read more]

Hi @dani68k, welcome to EnviroDIY.

I’ve not got any experience on the ATmega32u4, and as a small AVR processor I would think you would need to customize your development for it. SDI-12 bit banging is very sensitive (unrelaible) if the timing isn’t configured right. Possibly using the USART would be better for timeing, but configuring that is…[Read more]

Thanks to @ptomasula for fixing https://github.com/ODM2/ODM2DataSharingPortal/issues/658

If I understand it right, the internal redirection for  POST to MonitorMyWatershed.org/api/data-stream/ HTTP/1.1 got broken with the upgrade to v0.15.0, and a http response of 301 was returned, which ModularSensors doesn’t handle. Of course its not a good…[Read more]

@dan-wachusett Gosh just seeing this – seems like you got that Keller CTD.

Just wondering did you follow the advice given from https://www.envirodiy.org/topic/keller-ctd-sensor/#post-16332

Partly its decoding the layers of software. The keller protocol is used to access the Keller CTD map. I find it most helpful to compare and trace how…[Read more]

Some recent posts here explain the current difficult environment for calculating power usage on the mayfly as its dependent on a fast response from the server.

My implementation is to ensure that there is sufficient reservoir of power in the battery for taking…[Read more]

Well, I’m back at my desk, with a Mayfly and powered it up, and I’m posting to

Host: monitormywatershed.org

and getting

If I change it to

@rogers1313  gosh its all depends on the software you are using – what’s the version of software and the source. Since its open source software and hardware, and you can look at the software – its possible to guestimate those answers. Then since its software that causes the most power usage, it needs testing.

For a turnkey system, assembled off…[Read more]

I  wonder if there has been further insight.?

It seems a real challenge to phrase how to have real world reliability. It seems to be such a hard concept to discuss and define how to get there. Its a standard Computer Engineering problem, and it typically requires a commitment to make it happen, and a reference model to test the implementation.

Thanks for looking into it.

I’m in the UK for my Uncle who had a stroke, and I took off very quickly from California,  and not likely to get back before the end of May after his funeral. I haven’t brought any tools to see what the response are from the server.

It seems very unlikely that 5 systems would all stop transmitting by themselves. My…[Read more]
