for the JavaScript file upload-ssl-certs-to-bg96.js
All three files have to be provided in PEM format. As this format is in ASCII, you can just cut and paste the contents to the JavaScript source code.
Then transfer the code to the device (using the Espruino IDE) and call function
uploadCertificates();
The files will be saved to the device as cert.pem, key.pem and cacert.pem and can be used in a later step to configure the SSL connection options for the embedded MQTT stack.

Espruino is a JavaScript interpreter for low-power Microcontrollers. This site is both a support community for Espruino and a place to share what you are working on.
Some IoT platforms like AWS IoT require you to authenicate with X.509 client certificates when using MQTT as communication protocol for your devices.
The Quectel BG96 module on the RAK8212 already has an embedded MQTT stack, so there is no need for using a MQTT library on the device’s MCU.
The BG96 module supports client and server side authentication using X.509 certificates. The following files must be provided:
The challenge is: How can these files be transfered to the BG96 module’s file system?
Having Espruino installed on the RAK8212, this is not a complicated task. Check my github account at
