channel cn500-510

Question

I am using the chipstack v4 version, which defaults to using cn470, but also requires cn500-510. How can I add relevant configurations in the configuration file? My cn500-510 channel is shown in the picture

See page 43 of regional params. 470-490 MHz is valid for uplinks.

500-505 MHz does not fit the defined CN470 channel plan.

To use a different frequency range a new plan would need to be defined in code.

CN500-510 is not a LoRaWAN standard frequency band.

China deploys LoRaWAN optimal frequency bands: uplink 486.3~~487.7MHz, downlink 506.7~~508.1MHz
