We purchased K902 modules and developed a board with ethernet according to the datasheet. We used the command
tst help
ant - antenna status check
config imu param
config debug param
config dr param
config flash param
help - print online help
config imu param
config net param
rtc check
config rtk param
config com link cpu
OK!
Command accepted! Port: COM1
tst net on
OK!
Command accepted! Port: COM1.
eth init.
Now the question is how to configure the K902 to operate on the network (IP address, port, DHCP). Because we see on the oscilloscope that the carrier on TX-, TX+, RX-, and RX+ is active, the circuit is working and only the module configuration commands are needed. #K902
