Just a crazy idea:
If you follow the download link from HughB in #1 ( https://www.icofchina.com/d/file/xiazai/2020-09-22/26ac3f347aca9fc6c3a23db296b0dec0.zip?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB ), you will get a .zip file which contains GnssToolKit3.exe . If you start it, it waits for a connection to a COM port.
[crazy on]
Would it be possible to route the internal COM ports of the watch via Bluetooth serial to GnssToolKit3.exe ?
[/crazy off]
If this is working, it should be possible to look at the communication with a com port sniffer and eventually get hints for the CASIC communication or (I'm dreaming) AGPS.
btw: You can set GnssToolKit3.exe to English with the rightmost menu entry, 3rd item and restart of the program.
While searching the internet for "gnss-aide.com" it seems that also ublox devices use this service. Which AGPS provider does the Bangle.js 1 use?
