I noticed that you have enabled the SSL certificate verification function, but I did not see that you imported the SSL certificate in the code. Is this the problem?

kedzior-io · 2021-01-30T12:45:21Z

@lewisxhe it can be an issue actually.

MS recommends these for Azure IOT https://github.com/Azure/azure-iot-sdk-c/blob/master/certs/certs.c

Is there any code sample I could use to import those?

lewisxhe · 2021-01-30T13:01:13Z

I have written an example, but I still encounter a little problem. You can refer to the documentation to test it first, and I will share it if I finish it.

kedzior-io · 2021-01-30T20:06:19Z

@lewisxhe thank you!

kedzior-io · 2021-02-24T21:52:01Z

@lewisxhe any luck?

lewisxhe · 2021-02-25T01:06:58Z

I have no luck.

SIM800L is not in the latest firmware and does not have built-in MQTT service. Therefore, the built-in MQTT service cannot be used, which is owned by SIM800C.
When I use a similar SIM800C to connect to a server that needs to verify the certificate key, I encountered the problem of the maximum 32-character limit for importing private keys. (This option limits most IOT clouds)

lewisxhe · 2021-02-25T01:11:53Z

I can’t use Azure IOT. I know whether Azure IOT can enable key authentication instead of certificate verification?

kedzior-io · 2021-04-22T17:53:33Z

@lewisxhe
https://docs.microsoft.com/en-us/azure/iot-hub/iot-hub-devguide-security

So if I understand i well to connect to Azure IOT I need to establish connection over secure port 8883 - that requires to import SSL certificate. If that's the case do you have any example out there?

Assuming that SSL certificate is all good the connection gets established by specifying:

username
password

So it's down to using commands here https://cdn-shop.adafruit.com/product-files/2637/SIM800+Series_FS_Application+Note_V1.01.pdf

What could help is this I guess : https://github.com/vshymanskyy/TinyGSM/blob/master/examples/more/SIM800_SslSetCert/SIM800_SslSetCert.ino

Certificated needed would be this one: https://github.com/Azure/azure-iot-sdk-c/blob/master/certs/certs.c

Actually I have just updated the code (untested): https://github.com/kedzior-io/esp32-sim800l-tinygsm-azure-iot-hub-mqtt-ssl/blob/master/mqtt-azure.ino#L59

Does it make sense?

ThamerLeme · 2021-06-01T11:41:02Z

Hey guys, any updates? I am running the same issue and couldn't find a solution

kedzior-io · 2021-06-01T11:45:49Z

@ThamerLeme nope.
I gave up and went for different device that uses SIM7000G and was able to avoid this problem but now there is another 😭

Xinyuan-LilyGO/LilyGO-T-SIM7000G#114

ThamerLeme · 2021-06-01T11:49:35Z

@kedzior-io thats sad...
Thanks for the reply

SebastienBrun · 2022-04-19T11:38:57Z

Any news about the problem SIM800L and MQTTS ? Thank you :(

NoNamedCat · 2022-05-07T09:58:24Z

Bump

SebastienBrun · 2022-05-07T12:38:30Z

I finally changed my module sim800 to sim7000g...
Mqtts work fine!

NoNamedCat · 2022-05-11T13:04:43Z

So is not possible to use a sim800l on AWS?

kedzior-io · 2022-05-11T13:17:59Z

@SebastienBrun yes I did the same used SIM7000G and it works with self hosted MQTT broker (Mosquitto). I haven't been able to get it working with Azure IOT though:

Here I get DNS errors when using Azure IOT Free Tier (it's more than enough for my needs)
Xinyuan-LilyGO/LilyGO-T-SIM7000G#120

Here I get issues when connected to Mosquitto:
Xinyuan-LilyGO/LilyGO-T-SIM7000G#163

It works but it gets constant re-connects.

Where you able to get it running smoothly?

@NoNamedCat
Sorry I have no idea if it would work with AWS.

SebastienBrun · 2022-05-11T14:43:02Z

@kedzior-io
I had the same issue, constantly reconnect !

For me the issue was : i connected two devices with the same username/password and client-ID.

Other thing , i authorized on my mosquitto server to self define your own client-ID
I don't know how to configure that on self hosted mosquitto, I use mosquitto on stackhero.io service.

But this example is using SIM7000g not the sim800l. And is not using certificates (tls 1.2). I have a problem with the connection when i introduce the certificates in the secure_presentation_layer.

NoNamedCat · 2022-05-11T23:03:02Z

This is the log that i have when i comment this lines:

  secure_presentation_layer.setCACert(root_ca);
  secure_presentation_layer.setCertificate(client_cert_pem_start);    //x509 client Certificate
  secure_presentation_layer.setPrivateKey(client_key_pem_start);      //x509 client key
