Getting up to speed on the Arduino MKR 1400. It’s an acceptable substitute right now for the Dash, and hopefully will allow a smooth transition to the MKR 1500 and its CAT M1 modem.
So far, I’ve managed to establish two-way communication between the board and the Hologram cloud.
However, on the Dash it was possible to use a common code base for multiple devices, since no key was required to connect to Hologram. Using the MKR 1400, the GPRS credentials require a device key, so a common code base is not immediately possible, it seems, since each device needs to have the device key hardcoded in.
Does anyone have any thoughts on how I might get around this, i.e., use a common code set so I can use the same software for multiple Arduino units?
