Has anyone looked to see if the SDI-12 library could be ported to the new RP2040 chip. Maybe that already works in its existing state, but I haven’t see it mentioned anywhere. This is the new IC that runs the RPi Pico and can be used via the Arduino language.

Can you provide more details especially in reference to your code and how you are connecting to thingspeak?

That is the version of XBee I use as well. They are very short supply. I only have some cause we bought a large supply of them bout a year ago. The dev board I use with mine to upgrade the cellular firmware and normal XCTU operations is the XBIB-CU-TH. Digi-Key has 200+ of those.

No, the apn would need to be loaded via XCTU or you can place it in the python code before the cellular connection action…
xbee.atcmd(“AN”, “hologram”) —–or whatever your apn is
conn = network.Cellular()

Any arduino code you would like to use. The key is to identify which serial port you have connected to the XBee. For instance if you have it connected to Serial1 then you would want to print out the statements you want sent to Thingspeak like so…

it seems I have to add your contact email to allow the share. I’ll see if I can post the zip file. It didn’t like the .py files before

I misspoke on the DC/DC supply. It is a Meanwell DDR-15G-5. Pic of the guts on that polycase is attached.

We use a polycase 12x10x6 customized enclosure for under $85 with everything predrilled https://www.polycase.com/yh-121006.
We made a custom din rail bracket to hold the two batteries. 10W panel for solar but charger will accommodate up to 30W

12V to 5V is a DC/DC Din Rail supply P/N: MDR-20-5. The board takes in 5V and and has a 3.3V LDO onboard for those 3.3V parts that pull more than the teensy 3.3V output can provide.

@neilh,
Yes, we have solar to the charger and into (2)12V 9aH batteries (in parallel). The Teensy and Xbee are on a custom motherboard we designed. Has lots of the IO broken out and spots for Adafruit GPS, RTC battery, ESP32 (older requirement) and Wiz850io Ethernet.

@Both
Working on the google drive link for the XBee files if either one of you want them in the future.

Setting up this topic at the request of @neilh to discuss advances we have made using the Teensy 3.5 board for logging data and have been able to establish remote updating, as well as, a bootloader that allows for boot from the loaded program, but checks for boot file on the uSD card first as a potential update to the program.
Bootloader is taken…[Read more]

Are these Verizon Jetpacks with Wifi or do your modems have a serial connection? We started out with AWS, Verizon Jetpacks w/WiFi and the ESP32. It worked, we just didn’t have an active AWS contract in place so the free trial accounts were running out of room for us. We at that point just set up an internal MQTT Broker so we (National Weather…[Read more]

@dan
I agree with @neilh in that AWS can be a little cumbersome. I have used it with the ESP32 platforms in the past via WiFi, but in the end opted for using other end points than AWS. Lots of free dashboards out there for starting out and learning. Most of the really nice ones start adding costs once you decide to scale up the number of data…[Read more]

I’ll put the files up on a google drive and send a link for a folder to download here in a bit.
Yes, micro-python gives you lots of option. We use TLS1.2 encryption of our data, run a broker at one of our regional headquarters and also have a FTP-Secure server to remotely update both the XBee and the Teensy 3.5 processor I use as the…[Read more]

Everything I was talking about is MQTT with Thingspeak. I tested it on my Thingspeak connection I created. It was just allowing the micro-python code in the Xbee to handle all the network and MQTT items vice using the AT commands from the MayFly to the Xbee as it looks like is happening in the enviroDIY libraries.
