@ayechan – do you have a specific problem or are you looking for general instructions?  If you have a specific problem, please create a new topic with a detailed description of your setup and problem.

If you are looking for instructions, start by reading the sensor manual provided by Yosemitech.  If possible, connect the sensor to you computer u…[Read more]

That configuration looks good to me.  Let me know if you see any bugs I can smash.

Yes, that’s what it should have done.  I don’t see any obvious reason why it wouldn’t have, other than that it clearly didn’t.  The single battery measurement was on the low side (only 3.6) so it is possible that your battery just died.

I made an issue for myself to fix this: https://github.com/EnviroDIY/ModularSensors/issues/304  Unfortunately, that doesn’t give you back lost data.

Oh.  Oops.

The data was probably rejected because of the timestamp.  The clock resets itself to 2000-01-01T00:00:00 – but then ModularSensors applied a negative offset to it assuming you wanted the file to be in UTC-6 with an RTC set in UTC.   That caused a weird rollover (roll-under?) giving you a timestamp of 2000-01-01 252:211:00.  Moni…[Read more]

I didn’t try running it, but there’s nothing that jumps out at me in a very quick glance through the code.  Did the SD card have data on it?

That does seem worthy of a new thread; those are the Bee’s we’re using so I’m more familiar with them.  They’re easier for us to get (no international shipping), similar in price, have carrier certification, and have a secondary processor that takes care of the baud rate trouble.

I don’t think we’ve had any yet that were DOA, but we have managed…[Read more]

Was anything recorded on the SD card?

If you remove both the coin battery and the mayfly loses power, even for an instant, the clock will reset to Jan 1, 2000 0:00:00.

The coin battery isn’t necessary if there’s another power supply, but it’s very convenient to power the clock with its own battery so that you don’t have to reset the clock every time you turn the Mayfly off.  The…[Read more]

As for T-Mobile’s 2G, the most recent I’ve found says no guarantee past the end of this year.  A while ago they were saying that they would maintain the same coverage area for 2G up until the sunset, but we keep having more sites without coverage.

I’m sorry!  The SIM800 definitely has quirks, but it’s better than this.  We have had better luck with the Mayfly and Digi LTE XBee3’s than you have had with the UBee, but I’ve spent a lot of time tweaking things to figure out what works.

It’s funny, we were on a phone call at one point with a group at Oregon State that was just beginning to l…[Read more]

I’m sorry, but you keep saying things that are unclear and incomplete which makes it very frustrating for me in trying to help you. You seem to know very little about what you have so it’s difficult for me to believe that you do have correct wiring and code.

Do you have or have you read the manual from Yosemitch for your sensor and do you…[Read more]

Are you using Arduino core on your ESP8266 or are you using NodeMCU Lua? They are completely different firmwares; Arduino core uses cpp and has many libraries that parallel functionality to an AVR Arduino board like the Arduino Uno. NodeMCU uses Lua script.

I use softwareserial and ive heard that it work but dont really know.

There is a…[Read more]

I am so very unimpressed with the SARA R410. It does not deserve its name.

Oh, no, the hold for the URC *is* working. It’s just not holding for long enough. It gives up after 75s and the code wasn’t smart enough to differentiate between a ‘0’ = nothing in the returned buffer and ‘0’ = the modem returned that it opened the socket with 0 errors. The CSQ responses show good signal you’re already registered on the network…[Read more]

Now it’s the asynchronous open that’s causing trouble. That *should* be blocking. The program should not continue until the URC arrives. I will need to test that more.

Anyway, another change in TinyGSM:

    // Use an asynchronous open to reduce the number of terminal freeze-ups
    // This is still blocking until the URC arrives
    // The…

ModularSensors does NOT work using an ESP8266 of any flavor, including NodeMCU, as the main processor.

The Yosemitech library might; I’ve never tried.

Oh, and yes, the issue with NIST is really common. There have been a few GitHub issues about it. I’m trying to connect over TCP to the daytime server. That server is designed to respond to any incoming connection on port 37 with 4 bytes representing the current timestamp and immediately close the connection. A lot of the time the various…[Read more]

It’s awesome that you’ve created your own publisher!

Ok. I see what’s happening. The R410M takes a *really* long time to close sockets (like 2 minutes). To speed things up, I call the socket close “asynchronously” – that is, tell it to close and move on. But what I think is happening here is that I’m telling the socket to close before opening…[Read more]

Doh. Yes, I thought of that as I was driving home. Do add the lines setting the wake pin high.

Do you know what version of the firmware you’re running? To check, you can either hook it up to the u-blox m-center on your computer, run a pass through sketch and send it the commands AT+CGMR? and AT+GMR?, or tack these lines in after the modem…[Read more]
