I’m also in this situation where I can’t use the DASH board because HOLOGRAM SIM does not cover my area/country. Hence, I need to use a local telco carrier’s SIM. Thus I need to change the APN setting at the Hologram’s System Firmware level but the DASH FIRMWARE is nowhere to be downloaded yet.
I found another topic here where a PASSTHROUGH FIRMWARE was discussed, enabling the passing of AT commands directly to UBLOX so that APN setting and other carrier-related credentials can be easily coded… I tried this path, but the said passthrough ‘user’ firmware have made my DASH board not reachable by ARDUINO IDE…
I’m a bit running out of time to port my Prototype from ADAFRUIT FONA FEATHER to HOLOGRAM DASH and hopefully you guys can help me sort things out.
