Description
smartDF is an iPad-based direction-finding app for locating emergency and radio frequency signal sources. It connects to compatible Rhotheta DF hardware to provide real-time bearings, frequency scanning and decoding, and mapping tools that support search operations, including aviation chart overlays, breadcrumb tracking, replay, and offline maps.

RDF AND DCU COMMUNICATION IMPROVEMENTS • Improved RS-232 command timing and reliability for frequency, squelch, scan, decode, and DCU page changes. • Improved startup communication, RDF identity retrieval, and return-to-bearing behavior after reading DCU and Antenna Unit information. • Improved squelch and scan feedback so requested changes remain visible while the DCU processes them. • Reduced unnecessary command traffic and improved Secondary control responsiveness. LINES OF BEARING IMPROVEMENTS • Improved saving lines of bearing during brief signal, GPS, heading, communication, or map interruptions. • Improved saved-bearing rendering after temporary map-style reloads. • Improved synchronization of saved bearing lines between Primary and Secondary iPads. • Newly saved bearing lines are no longer automatically selected. FIXES AND RELIABILITY • Fixed COSPAS-SARSAT decoding in RDF Test Mode. • Fixed possible crashes involving repeated error or warning details and Advanced Settings color changes. • Fixed an issue where the active bearing line could briefly disappear during temporary data gaps. • Fixed the GPS indicator incorrectly showing an error while the iPad was stationary with a valid position. • Improved portrait layout alignment and Mapbox attribution positioning. • Removed an offline-map message that could briefly appear over the active map. COMPATIBILITY AND APP STORE IMPROVEMENTS • Added support for iPadOS 17 and newer. • Updated Bluetooth, local-network, and location permission descriptions. • Improved privacy declarations, release logging, font packaging, and App Store compatibility. • Additional stability and performance improvements.
