Thank you so much.

I am not using the AWS stuff for now but I will be deploying mosquitto on cloud at some time.
if this old firmware create problem at that point, I will update the firmware.
Thank you again.

Yes, those are because of the old firmware. If you’ve got it working, it may not be worth updating, but it should eliminate those work-around.

If you want to use custom SSL certificates, upgrade. The only way to push custom certificates with the old firmware (or with an ESP8266) is to use a python script to write the memory blocks with the new…[Read more]

I am using EnviroDIY fork. Until now everything is working. I am able to make both http post, and mqtt connection.
I checked and mine esp32 firmware version is 2.4.0. So,Is it because of this lower version, I had to do some hack around for ssl connection?
Below is the part of workaround I coded to make it work with hydroserver.

Are you using the original TinyGSM or the EnviroDIY fork? The EnviroDIY fork is far ahead of the original right now.  (It’s on my to-do list to have a proper PR.)

I’d (strongly) recommend updating your AT firmware.  The current version of TinyGSM on the EnivroDIY fork expects firmware >= 3.2.0.0.  Because of changes in the memory mapping for SS…[Read more]

I have.
Before opening a tcp connection, the Socket Receiving Mode should be made to 1 (passive mode). I have no idea why it works only while doing this. But it works.

Were you able to connect to your MQTT broker?

It looks like you’re working from the modem component within Modular Sensors.  That component wraps TinyGSM and adds physical pin support for power management.  But the wrapping makes it a bit confusing because you have to access objects with pointers and creator functions.  And if you’re trying to us…[Read more]

Ah. That example is written for the current “master” branch of the library, not the latest polished release.  I’m way overdue for a new release, but there are some bugs I still need to fix.

Try starting from this example instead, which is matched to library release 0.37.0:  h…[Read more]

We’re really excited to partner with Labcrafter so they can be a source of our products to people in Europe.  As for sensors, the Maxbotix MB7389 you mentioned is probably your best bet for low cost ultrasonic rangefinding.  Just be sure to order the TTL version so it’ll work straight into the Mayfly board (the RS232 sensor would require an i…[Read more]

Never mind. The wifi worked. I used AT+CWMODE? and change it from SoftAP to Station mode.
But I am struggling to use this to connect to mqtt broker.

The ESP32 does.  It’s also a currently supported product and very widely available.  You can get very cheap ESP32 breakout boards in a variety of shapes and sizes.  There are several flavors depending on how much power you need, but they can all do a basic secure post request.  You could even use the older, even cheaper ESP8266.

If you’re usi…[Read more]

Thanks for the reply.
So, how do I even do POST request to server running on the web? Are there any Wifi modules that are alternative to Xbee that supports SecureClient?
