Hello,
I have some questions before buying this module:
-
I need the ability to, obviously, send sms messages to different recipients and I need to read incoming messages, precisely to forward some sms if they are from specified senders.
-
I’m using a raspberry pi3 b+ with its power supply, do I need to buy another power supply for the sim800l module?
-
can I follow this guide? SMS and a recommended modem
-
is there a “better” hardware module model to buy?
-
does exists a case to enclose both raspberry and the sim800l module?
Thank you
