New and Improved BLE App. (#1524)
* First BLE work * Adding new fsk proc WIP * Reverting ble stuff * Initial compile working * more work. * Adding waterfall for debug * more edits to debug * Work to get widgets to show. * cleanup before attempting diff fsk modulation method * Temporary debug to learn how decimation scales. * Tab view for console and spectrum. Spectrum still not working right. * Fixed spectrum offset. * Added audio sampling rate increments to freqman * Added overriding range for frequency field and working off deviation * BLE cleanup. Got PDU parsing. * Parsing CRC * forgot : * Removing AA again because cluttering UI * fix compile * attempt at throttling. * WIP changes. * Decimating by 4 to handle issue with overloading. * Attempt to parse MAC still needs work. * Small fixes. MAC still wrong. * Fixed invalid indexing on Symbols. * List view of BLE Mac Addresses * Added Channel Option and improved GUI header. * renaming to dB and fixing some warnings. * Advertisements only. * Initial cut of BLE Advertisement scan app. * Copyrights * formatting correctly in association to clang13 * Fixing warning and hiding fsk rx. * spacing * Removing some cmake install files that weren't suppose to be there. * missed some. * Added name to about. * Edits for PR review pt.1 * Refactor ORing with 0 doesn't make sense. * remove parenthesis * More PR Review changes. * Fix compiler error. * PR Review edits. * PR review changes. * Fixes. * Unneeded ; * Update ui_about_simple.cpp --------- Co-authored-by: jLynx <admin@jlynx.net>
