it worked when we used the really simple code, when we tested by using https://github.com/wklenk/rak8212-espruino-nb-iot/blob/master/upload-ssl-certs-to-bg96.js.
it can work after modifying a little for Singapore Cat-M1. even worked fine after doing "save", but it hanged when we restarted the board by turning off and turn on power
