Hi everyone, I have installed a GPS card in the mini PCIe slot of a RB411U.
The PCIe GPS emits a raw GPS signal in ubx binary format at a frequency of 1Hz.
In port I see the device as USB3 and so I activated a remote-access for sending GPS data on a TCP port.
port> print
Flags: I - inactive
DEVICE NAME CHANNELS USED-BY BAUD-RATE
0 serial0 1 auto
1 usb3 1 remote-access 115200
At the start of the routeboard, to make the data forwarding work, I have to set the rfc2217 protocol. In fact, if I initially set the raw protocol, the acquisition stops immediately.
But with the rfc2217 protocol the GPS data are not acquired correctly and I cannot use them to make the GPS position. So I have to change the protocol from rfc2217 to raw and everything works fine. Would anyone be able to explain why?
Thank you in advance
