## Fixes: #17447 Updated the SX127X demo documentation to include an overview, default configuration settings, short-range FSK testing recommendations, and troubleshooting tips. The default TX power has been changed from 14 dBm to 17 dBm, and CRC is now enabled by default. These changes aim to improve user experience and ensure robust communication for the SX127X radio driver. ## Summary - Raise the default SX127X TX power by setting `CONFIG_LPWAN_SX127X_TXPOWER_DEFAULT` from 14 dBm to 17 dBm. - Enable CRC by default by setting `CONFIG_LPWAN_SX127X_CRCON` from 0 to 1. - Expand `sx127x_demo` documentation with defaults, short-range FSK recommendations, and troubleshooting, following the behavior observed and recommendations in [apache/nuttx#17447](https://github.com/apache/nuttx/issues/17447). ## Impact - SX127X users get a stronger and more reliable default link (higher RSSI at short range). - CRC-on by default improves payload integrity by rejecting corrupted frames. - Boards that already override TX power or CRC remain unaffected; users needing CRC off can still explicitly set `CONFIG_LPWAN_SX127X_CRCON=0`. -- This is an automated message from the Apache Git Service.
