Hi @matsujirushi,
All I can say is Wow ! The document is similar to the Seeed wiki but written in a much clearer way.
Is it possible for Seeed to adopt it I wonder.?
I wonder if the piece about Soracom is applicable to everyone ?
I am in Taiwan, so I have a SIM card from Chunghwa, the main mobile network provider. It has the best coverage in TW.
So, will Soracom allow people on different networks use their aggregation site ?
In any case the link to MQTT is especially useful because the system I am using sends a JSON file every 5 minutes to a central site not dissimilar to Soraccom, and the transmission protocol is MQTT.
