@vogelrnws Ok, thank you. If you need my email, zholloman54@gmail.com

@vogelrnws I was spending some time looking at the cellular stuff and I decided I’d try to use the python example you used, but I can’t seem to access the files through the Google Drive. Also, I don’t think I currently have a python editor. What is a good one that you would suggest? Thanks

@neilh20 Ok, that sounds good. I just sent the details to your email. Let me know if it still works.

@vogelrnws Thank you for sending that. I’ll be sure to take a look at it if ThingSpeak doesn’t work.

@neilh20 I tried running the code with your ModularSensors library, and it still didn’t work. The apn I’m using is hologram. If I am using a Hologram SIM card, is that correct, or should I change the source to something else? Also, what is Tera-term with Timestamp, and is that something I should consider using?

And also, one more question. Is ThingSpeak with API different that ThingSpeak with MQTT? Right now, it looks like I’m using the MQTT connection.

Hi there @vogelrnws. Honestly, It’d be awesome if you could send that code. I’m still considering my options on the method to publish the data, but that could be helpful!

@neilh20, ok! I’ll try that. For some reason (not really sure why), the code all of a sudden started saying that it couldn’t connect to the internet for clock sync. I’m looking into that, so I’ll get back to you once I fix that. Thank you again!

Hey @neilh20. I just had a thought. The fact that the software works with the Digi WiFi S6B. Do you think that means its an issue with the actual cellular connection as opposed to the code?

Hi there @neilh20. Thanks for your response, sorry I couldn’t get to it until now. I spent some time on the code, and I tried the code with the 0.28.5 version of the EnviroDIY ModularSensors library just to see if anything changed. It still isn’t uploading to ThingSpeak though. I tried the 0.30.0 version of the ModularSensors library, alongside the StreamDebugger as well, here’s the output of the code (excluding the ThingSpeak data). It doesn’t look that much different.

That’s very strange that the code worked with the Digi Wifi module. Any other suggestions are greatly appreciated! And if you see anything that I did wrong with the code, please let me know! I’m still rather new to this.

Hi @neilh20, thanks for all your help! Yeah, I think I replaced the channel key in the trace with the thingSpeakChannelKey for the forum. I’m looking at the Topic [41] thing and I see the key in the topic channels/…

Here’s the platformIO file.

@vogelrnws

Hi there! Yeah I registered the MQTT device via ThingSpeak. I used the MQTT Explorer you suggested and I was able to post some data to Thingspeak by typing literal values into the Explorer. This leads me to think that it’s an issue with the Mayfly code.

@neilh20 I’m curious as to how you set up the ThingSpeak using POST. I’m not really committed to the MQTT platform, and I’m curious how you set your’s up.

Hey @neilh20. Thanks for looking at. Yeah, I already had the keys and the channel ID in the code, I just took them out for the forum. Sorry, I understand that could have been confusing. Other than that, is there anything else you could see it being?
