Sequence:
- Host sends CRSF_FRAMETYPE_DEVICE_PING to discover connected devices, and determine the number of configurable values available.
- All devices matching the Extended Destination field of the PING request respond with their CRSF_FRAMETYPE_DEVICE_INFO packets.
- For each parameter index
- Host queries parameter index with CRSF_FRAMETYPE_PARAMETER_READ, chunk 0
- Device responds with CRSF_FRAMETYPE_PARAMETER_SETTINGS_ENTRY chunk
- Host may need to request additional chunks to complete the parameter information if the SETTINGS_ENTRY indicated non-zero chunks remaining
- To set a value, host sends an CRSF_FRAMETYPE_PARAMETER_WRITE with updated value
- ExpressLRS: Host should requery all same-level parameters to determine if the parameter change has altered other sibling parameter values / options
