Hi there,
I'm trying to connect a Arduino Mega2560 to a development board SIM7020E
same as this Placa de desarrollo SIMCOM SIM7020E M2M B1/B3/B5/B8/B20/B28 SMT LTE NB IoT, módulo competitivo con SIM800C, nuevo y Original| | - AliExpress
...but I need help to hardware connection and how to test communication to Vodafone IoT network (I have a enabled SIMCard from Vodafone New Zealand).
First time in front of IoT and even googleing I found always same example using MKR and T-Mobile.
Any BASIC recommendations just to right hardware connection and IoT network tests ?.
Thank you in advance.
