SIM7000E Sending AT commands

Support DFRobot
6

Sure, appreciate the help!

  1. The code I attempted to use was from the DFRobot Wiki (https://wiki.dfrobot.com/SIM7000_Arduino_NB-IoT_LTE_GPRS_Expansion_Shield_SKU__DFR0505_DFR0572). For some reason had a bunch of issues compiling this with the default library the wiki provides. Don’t have access to my system at the moment to see any errors.
    Issues in sending AT commands to SIM7000E - This is the broken code I was referring to - with the actual reading and sending of AT commands to the device.

  2. Both sims were indeed activated. I haven’t actually been able to test these in a device, as they are full size (for the sim module) and I’d like to avoid using an adapter in the device. However, I will look at this, thanks for the suggestion.

  3. The signal strength can be found using the library command sim7000.checkSignalQuality();, provided in one of the examples codes.

The module is a shield that sits directly on top of the Arduino, all pins connected so it shouldn’t be an issue there.

Thanks dave!
