Installing SSL Certificate(.pfx file) in Spresene main Board

[Noor]

Hi,

I have interfaced ESP-01 WiFi module with SPresense main Board. I wish to connect this to my office Network (SEN). SO to do this , I need to install SSL certificate in Spresense. What is the exact procedure to install SSL certifcate which is in .pfx format in Spresense using either SDK or Arduino IDE.

Kindly help me out with this.

Hello, @Noor

Sorry for the delayed response.
I believe you need to upload the certificate to the esp board using the AT commands.
The ESP8266 library we have adapted to Spresense at https://github.com/kamtom480/ITEADLIB_Arduino_WeeESP8266 communicates to the ESP board using AT commands, but it does not have a function to send an SSL certificate.

Some googling led me to this
https://github.com/JiriBilek/ESP_ATMod#atcipsslcert---load-query-or-delete-tls-ca-certificate

This person seems to explain how to do this, but you would have to look deeper into it.

@Noor and @jp04

You two are using two different WiFi board options, but you are dealing with the same issue of how to upload the certificates related to SSL connections by using AT command.

I thought you might benefit from getting in touch.
