Hello, did anybody try to use MicroPython with the Nucleo F429ZI board (as shown here https://twitter.com/_rac01/status/789091494108000256 ? With a lot of RAM and Ethernet port + proven ability to run mbedtls (in mbed OS5 example) it looks like a great IoT board. Interested in any input! best regard...

I had a look at the MicroPython port for the ATMEL SAMD21 (as on the Adafruit Feather M0 WiFi) described here https://www.youtube.com/watch?v=fYw-gmrtuT4 . After I asked Tony DiCola about TLS support ( https://twitter.com/tdicola/status/782425341503627264 ) I wonder whether TLS can / could actually ...

Hello Dave, hello Neil, great to see your work! As for both the K64F mbed board as well as the Teensy - I'm especially interested in the connectivity / TLS part. - Do you have TLS support over Ethernet for the K64F included? I tested this with mbedtls and mbed on the K64F - so the MCU capabilities a...

Great to see that!

Does the WiFi connectivity include TLS support? And if yes - is it done by the MCU (using an ssl lib) or using the features of the WiFi chipset (such as for CC3200)?

Hi Jim,

thank you! As I'm involved in the development of the SAP HCP IoT Services and especially its StarterKit https://github.com/SAP/iot-starterkit - just let me know if you are running into issues! Might be able to help!

I'll be working (and sharing information) on MQTT (in case of the SAP HCP IoT Services as MQTT over WebSockets/TLS) as well. We have standard Python (Paho) clients in the Starterkit - but usage with WiPy etc. will be nice as well.

That's quite understood. As one resource I can refer to the SAP IoT Starterkit https://github.com/SAP/iot-starterkit that combines step by step instructions for setting up the Cloud part (which is in a free trial environment) with several (also Python) code snippets and ready-to-run applications. So...

I managed to have the WiPy interact with the SAP IoT Services ( https://github.com/SAP/iot-starterkit ) via a bi-directional TLS/WebSocket wss:// connection. See https://twitter.com/_rac01/status/773478655326580736 Many thanks to pfalcon for hints + the starting point https://github.com/micropython/...

It's working now! https://twitter.com/_rac01/status/773427887701712896 Many thanks to pfalcon for the support and https://github.com/micropython/webrepl as a starting point. For my purposes I had to modify: - add OAuth authentication in wss setup - use text (instead of binary) frames - WebSocket mas...

Meanwhile there is a 1st interaction on the WiPy as well.
