MQTT with TLS on BX3105

IoT Modules WiFi and Bluetooth Modules

Hi Eric

I worked through my local distributor and got direct information from SW in France.

The BX3105 is not able to connect to AWS IOT. There is a bug in the FW of the BX.

I am nou unsing the ODIN module from U-Blox with exactly the same cert files and settings and have a perfect connection to AWS IOT MQTT.

I hope SW will release new FW that works, but is very disappointed that they did not check their FW before releasing it.

Regards

Are you running FW version 2.6.3 the older FW gives an error when loading certs. The other cause could be newlines as suggest by jyiyi

Thanks Bernard.

I’ll confirm with SW and see if they have a remedy. I’m also interested in the u-blox part, you’ve had good luck with it’s performance?

Regards,
Eric

Yes. The ODIN works well.

Have nothing to compare it to. But its been working as expected.

Will be doing some field trials in the coming weeks to check the stability under real world conditions.
