Summary

What is the use-case?

For troubleshooting I want to use https://github.com/anthonykirby/lora-packet to decode the bytes. Currently have a case where the net key and the app key are correct and suspect that the device is sending corrupt data so need to read the raw bytes to troubleshoot the issue

related to https://forum.chirpstack.io/t/how-to-troubleshoot-get-device-session-error-invalid-mic/12595/5

Implementation description

In the gateway frames tab just add another field that shows the raw bytes.

Can you implement this by yourself and make a pull request?

yes with some small guidance
