 - Also, it might be useful to disable CRC check for LoRa packets with `cfg.LoraEnableCrc` parameter equal to `false`. Some broken bits in one speech frame will cause audio being scrambled, it might be better then longer gap when complete packet is dropped.
 
 # KISS command extensions
-When `EnableKissExtensions` configuration parameter is set to `true` modem will send signal level reports through KISS command `0x30` and client application will be able to control modem by using KISS command `0x10`, this way client application (such as [Codec2 Walkie-Talkie](https://github.com/sh123/codec2_talkie)) can display signal levels and change modem parameters dynamically.
+When `EnableKissExtensions` configuration parameter is set to `true` modem will be able to handle SetHardware KISS command 6 for setting modem parameters and will send event about signal level with KISS command 7, both are operating on KISS port 0. This way client application (such as [Codec2 Walkie-Talkie](https://github.com/sh123/codec2_talkie)) can display signal levels and change modem parameters dynamically.
