Dear experts,

I wonder if it’s possible to use arduino or raspberry pi to get RTCM correction data from the internet (through GSM or wifi) and send to ZED-F9P (through Serial connection). Right now, the hookup guide only provide examples using mobile phone (through bluetooth connection) or PC (through usb to Serial connection).

If yes, is there any reading material or code base I can learn from?

Thank you in advance.

I apologize for the delay. Unfortunately, we do not currently have an explicit example of how to make this work. It could be possible to send the UNAVCO over serial to the RTK GPS module, but you’ll have to do the legwork for that specific application.
