nRF52832 with Simcom 2G module

[Milan]

Hi Team,

I want to connect the nRF52832 based custom board to AWS-IoT cloud.

The Simcom 2G module is interfaced with nRF52832 over UART.

Can someone guide me from where to start on this?

Start by learning to use the UART:

Hi Awneil,

Thanks for the response.

I am aware of the  UART communications and AT commands but AWS IoT has some specific requirements like SSL/TLS 1. Also, there are various SDKs from Nordic as well as Amazon. 

My doubt is which is the most appropriate SDK to use here?

[awneil]

As noted in the linked post, none of that is specific to Nordic.

Amazon AWS neither knows nor cares what hardware you use.

Same for the SIMCOM module.

If the SIMCOM module doesn't provide SSL/TLS, then you'll have to implement that - again, these are standard protocols that are entirely independent of the underlying hardware.

mbed provides a TLS implementation ...

Maybe Simcom has some code for connecting up to the AWS cloud? Or some other cloud?

I can naturally also recommend the shiny new nRF91 DK. We have an example that runs out of the box that connects to the nRF Cloud, which is running on AWS.

Hi Bjorn,

Thanks for the response.

The hardware is based on nRF52832 with Simcom module interfaced over UART.  Can you please direct me which nRF52 SDK will help me (out of many) considering AWS communication.

[Bjørn Kvaale]

We don't have any examples with an nRF52 connecting directly to the nRF Cloud. You will need some sort of gateway connection like a computer, a Raspberry Pi or a smartphone to connect the nRF52 to the AWS cloud. You naturally have the Simcom module to use as your gateway. I would take a look at one of these examples here. In addition, this video may be helpful.
