Hello everyone,
I hope you are all well.
I am looking to explore the possibility of creating a new GSM component that enables connection to an MQTT server for sending and receiving data. While Flowcode currently offers a basic GSM component, it's not sufficient for establishing internet connectivity or interacting with MQTT brokers with simple component commands.
I am willing to fund the development of this component and would greatly appreciate any efforts from those with the expertise to make the component.
Thanks in advance!
Regards
George

Re: GSM Component - GPRS and MQTT
It would be possible, I think...
Data is written to the GSM module via UART - and, with care, it would be possible to build the necessary data to send to post MQTT packets.
It might be slightly easier on something like an esp32 - using the http support?

Re: GSM Component - GPRS and MQTT
Hi
What module are you thinking on using?
Common ones use "AT" commands and can easily handle data connections. I've possibly discussed this before. You need a copy of the commands and ideally whilst developing either a PC running a terminal program, or a logic analyser to see/decode what's happening on pins (PC is easiest). Once you establish exactly what needs to be sent / captured it's a simple matter to create appropriate Macros.
Unfortunately the "AT" commands whilst relatively similar, do differ per module, even those from the same manufacturer. Therefore I don't think a single component would cover.

Edit...
Forgot to mention that depending on module it can take care of HTTPS for you.

Hello!
Thank you for your response.
I frequently use the SIM800L module but would like to switch to a compatible 4G module since 2G networks are declining. I am looking for a flowcode component that works with Microchip PIC 18F devices and off course any other family like ESP ATMEL..

George
