Does the GPS RTK2 send rtcm messages out using the qwiic by default?
I’m trying to eventually send rtcm using XBee S2C ‘s
I have 2 zed-f9p ‘s and I want to use one as a base station
to broadcast the corrections. - using the qwiic. Is this possible?
Typically those would use UART2, not I2C
I2C would require one unit to drive the interaction.
RTCM3 input is enabled by default, but output by the Base expects specific messages be enabled individually, and a static location set for 1005 to be enabled.
okay, thanks… I was trying to think how to even receive a continuous stream using i2c.
I’m trying to use the sparkfun xbee explorer usb-c to hold my xbees and connect this to the zed-fp9 rtcm stream. I guess I need to connect the zed to my arduino, get the rtcm, and then send it using the xbee. Or just connect xbee to zed. I’m not sure yet how to use the xbee yet.
I would think you could connect a XBee S2C to the BaseStation TX2 , CTS, and GND pins, and operate the 2 XBee radios in Transparent (AT) Mode. AT mode acts like a virtual wire, passing all serial data through exactly as it is received.
If you aren’t stuck on the F9P, you might take a look at the LG290P breakout or the PostCard, to add the L5 Band (L1/L2/L5/E6).
The PostCard also has ESPNow, which might be a “cheat button” to get you started in Base/Rover comms (for short range only) as you start testing…then migrate over to longer range radio (LoRa, XBee, etc) ?
The alternative would be to program the XBee configuration with the explorer, and then have it wired to the RTK2 via a simpler breakout board where you plumb the power and data connections.
ArduSimple had an Arduino shield format permitting direct plumbing and powering of an XBee on the board itself.
Thanks. I’ve found some things for getting started with transparent mode. It doesn’t seem like too much heavy lifting. Much appreciated.
I have sunken into the sparkfun digi xbee usb-c explorer, which has a convenient usb-c. And I like the qwiic and the board over all. It should be helpful for temp sensors, and displays. And won’t go to waste. Thanks very much.
I stop back after I get something going.
