RTK Express with SiK radios in busy environment

We have two RTK Expresses (https://www.sparkfun.com/products/18442) set up as a base station and a rover that are connected with the usual SiK radios (https://www.sparkfun.com/products/19032) and they work most of the time.

Recently, we were using them in an environment with multiple groups flying drones of all kinds, and the rover would not connect to the base station. I suspect that some of the drones were also using SiK style radios, which were interfering with ours.

Is setting a unique NetID with ATS3=xxx on both radios sufficient to prevent interference between multiple pairs of the SiKs?

Does the RTK Express set any of the radio parameters on the fly, or do parameters I set and write to EEPROM remain in effect?

Yes, that should be sufficient.

No. The RTK Express does not know what radio is connected to it. The RTK Express merely sends serial out the RADIO port to whatever is listening.

Cool that works.

Is there a way to pass commands through to the SiK radio if I’m connected to the RTK Express with a USB tty or Bluetooth connection?

Not currently, no.
