问题
I would like to know if there is any way to make a GPRS / GSM module (SIM800L) as a "default" connection in android things that allows browsing the internet and making requests using the Android libraries.
回答1:
Seems no, because as in this answer of Blundell described: the source code is not available for Developer Preview. But You can use UART and AT commands.
回答2:
This is possible. I have been able to integrate SIM800L TO RPI3 running Android Things via UART and AT commands. I am however using it for sending SMS and not for Internet connectivity. I do not see an issue in achieving that as well.
Hope this answers your question.
