I'm very interested in GPS topics (see my comments in http://forum.espruino.com/conversations/370398/ ) and wondering what's meant with "CASIC"?
Can it be used to implement Assisted GPS?
Forum and internet searches doesn't provide results for "CASIC".

I've google-translated this document https://m5stack.oss-cn-shenzhen.aliyuncs.com/resource/docs/datasheet/unit/Multimode_satellite_navigation_receiver_cn.pdf

There is description of both textual CAS* and binary CASIC messages and commands.

Thank you for the spec!
Just an idea: I've seen receivers that communicate with different baud rates on different channels. Do you have tried to communicate with all "well known" baud rates?
