I’m working on an Iot project where i need to interface GSM module with STM32 and Blynk, but i can’t find any supported packages for the stm32 only finds for Arduino, what should i do?
Have you tried searching this forum?
Pete.
Blynk library implementation is highly portable. You need several basic things to port it to any platform:
- APIs for socket connection (TCP, preferably with TLS) like send, recv, connect, close
- Ability to compile/link limited C++ (no rtti, exceptions, stl, etc)
Having this, it should take no longer than 1 day to integrate the Blynk protocol.
Cellular connectivity doesn’t require dynamic credentials provisioning implementation.
Thank you for your reply, but i don’t find it clear enough since the Blynk library at GitHub is totally dependent on the Arduino Platform
I would like to have documentation on how the implementation goes using MQTT
Direct MQTT connections are not supported by Blynk atm. We consider Blynk protocol superior to MQTT:
If absolutely needed, you should be able to use Node-Red to integrate with Blynk, i.e.:
However this workflow is broken in Blynk 2.0 (but we are working on improving this).
Would you please provide a documentation on how to implement Blynk Library on STM32F103C8T6 (Blue Pill) since it’s from the supported devices.
I have found a difficulty on how to use the Blynk library since it’s totally dependent on the Arduino platform (Avr)
Multiple options are possible:
- You can use Arduino framework on Blue Pill. With this setup, you can use TinyGSM as TCP/SSL API provider.
- Use your own drivers for the modem, tcp, ssl. Use blynk library as a reference implementation, port it over to your platform of choice. Blynk protocol is tiny and doesn’t depend much on the platform APIs.
I also updated my original reply with more details.
Okay great, but how i can use Arduino framework on Blue Pill i can’t find any references for that.
And if there is any Documentation for the Blynk Protocol and how it technically works
I haven’t find anything related to the Implementation of Blynk on STM32. All i have found is irrelevant to the application.
But, according to @Pavlo ”MQTT is scheduled for SEP 2021”
Hopefully, that will be an MQTT 3.11 implementation.
