I am attempting to use the recently committed support for RAK2287, using the us915 configuration. I am running into the error
thread 'main' panicked at 'called `Result::unwrap()` on an `Err` value: "lgw_txgain_setconf failed"', src/libcore/result.rs:1165:5
Not being very familiar with Rust, I am struggling to understand what might be missing from the configuration. Suggestions?
Thanks.
After enabling debug messages in the sx1302_hal source, I found the same issue in the comment in the GitHub pull request
the issue was mix_gain: 0 . it doesn’t like to be zero. I’ve set every mix_gain to 5
But this change did not make it into the pull request. So I am past that issue. However, now I am seeing (after adding some additional debug info):

thread 'main' panicked at 'called `Result::unwrap()` on an `Err` value: "the channels do not fit within the bandwidth of the two radios"', src/libcore/result.rs:1165:5
I am using us915 configuration. I don’t know why the channels do not fit. I’m not sure what this means. Is this an issue with my .toml file?
I really want to help get this working. A little guidance is requested.
Also, I have it building for aarch64. Once I get past these configuration issues, I will submit a pull request for those changes.
As I mentioned on GitHub, this new shield needs some additional work and I have just received all components to test this myself (https://github.com/brocaar/chirpstack-concentratord/pull/16).
