Hardware doesn’t live in a vacuum! And neither does the Hologram SIM! This section of the forum is about getting your non-Hologram hardware connected. An example of this is the SIM800L, a low cost (soon to be defunct because it’s 2G) modem.
For 3rd party interfaces and devices, please refer to the hardware you’re working with. For instance, if you’re trying to interface the Hologram Dash to a temperature sensor, please post it in the Dash category.
A general note: We will not be able to troubleshoot every device because we don’t own every device. So you will need to take extra care explaining your situation, including code, other sites you’ve searched in the past and logs of building up your project.
