ADSBee 1421 Firmware Version 0.3.11 Release Candidate 1

• Adds settings GUI to web console at adsbee.aero. Includes JSON settings dump capability with AT+SETTINGS?JSON.
• Add AT+LR_ENABLE command that enables tri-stating the LR2021 so that the SPI bus can be released without sleeping (which would normally be done via the SYNC line).
• Add settings integrity check with leading magic word and trailing CRC32.
• Enable watchdog before settings edit.
• Add method to reset settings struct by holding BOOTSEL on ADSBee 1421 programmer.

NOTE: This firmware update will erase your settings!

• Increase SUBG radio RX bandwidth and a few other parameters to match ADSBee 1090 UAT configuration.
• Change LR2021 to be interrupt serviced with non-blocking SPI.
• Add headroom to SUBG packet structure to avoid extraneous errors when receiving uplink packets.
• Add version stamping to ADSBee 1421 programmer artifacts.

ADSBee 1421 Firmware Version 0.3.8

• Add option to disable UAT uplink reception with AT+SUBG_MODE configuration parameters.
• Update datasheet.
• Improve ADSBee 1421 webpage.
• Fix issue with ADSBee 1421 programmer firmware that caused device settings and serial information to be erased after an update.

ADSBee 1421 Firmware Version 0.3.7

This is the first public release of firmware for the ADSBee 1421! This builds off of the previous private release (0.3.6) in the adsbee-lp1090 repo. This release substantially improves all around performance by finally adding optimization to release builds, and optimizes the decode / encode workflow for UAT uplink packets, which were taking a bunch of extra cycles previously.

• CMakeLists.txt defaults CMAKE_BUILD_TYPE to Release.
• fec.cpp: DecodeUplinkMessage now corrects the interleaved raw message in place (per-block scratch, scatter corrected codeword back) — the re-encode pass and its per-packet CONSOLE_INFO are gone from uat_packet.cpp. DeInterleaveUplinkMessage is static.
• comms_reporting.cpp: ReportRaw/ReportBeast/ReportGDL90Uplink return immediately with zero sinks; GDL90 just de-interleaves the already-corrected raw packet (no second RS pass, no 1 KB stack object). Beast UAT builders now take raw packet types (beast_utils.hh).
• comms.cpp/comms.hh: 8 KB software TX ring; writes are queued and the UART2 write callback chains segments; bounded wait then whole-write drop under true overload (counted); DrainConsoleTx waits for the ring; SetBaudRate cancels/reset; drains added before reboot/bootloader in adsbee.cpp.
• cc13x4_cc26x4_nortos.lds: STACKSIZE = 32768.
• AT+RX_STATS? now also reports max_loop_us, tx_stalls, tx_drops, tx_ring_hw (reset with =RESET).

ADSBee 1090 Firmware Version 0.9.0 (Stable)

It's finally here! Firmware version 0.9.0 is confirmed as working and stable, and provides dual band ADS-B with weather / traffic / all the goodies.

The contents of this release are identical to 0.9.0-rc19 except for the version number string being rolled to 0.9.0.

ADSBee 1090 Firmware 0.9.0 Release Candidate 19

This PR provides significant improvements to the Mode S demodulator and network uplink firmware stacks, allowing the ADSBee to process more Mode S messages per second (especially squitter packets), and process / upload them as necessary without overflowing internal queues. Users should notice a lot more squawk codes getting filled in, and higher packet rates in high traffic areas.

• Broaden the net for messages fed into the demodulator (accept incorrect word count values from demodulator in case it didn't stop in time).
• Add early flushing to packet reporting queues to prevent overflows that were dropping packets.
• Improve decoding of aircraft operational status messages on Mode S.
• Fix incorrect decoding of operational status messages that was showing aircraft as on ground.
• Improve labelling of handshake timeout messages for better diagnostics.
• Add serial logger script for monitoring multiple devices with coherent timestamping.
• Fix Mode S emitter category reported over GDL90.
• Update README (thanks @aymzhang )!

ADSBee 1090 Firmware Version 0.9.0 Release Candidate 18

• Fix lockup issue from RC17
• Add console line limit and firmware update overlay to web UI
• Update web UI styling (now includes dark mode option)
• Add web UI for changing feed parameters
• Add agents file
• Fix GDL90 errors with ownship and NIC
• Improve batched reporting behavior on ESP32 for increased packet throughput
• Add AircraftJSON protocol
• Add radar map and aircraft table to web UI

• John/fix web by @CoolNamesAllTaken in #187

Full Changelog: adsbee_1090-rc17...adsbee_1090-0.9.0-rc18

Additional changes carried over from from RC18:

• Improve ESP32 stability by removing re-entrant behavior that was causing stack overflows on high traffic devices running ethernet.
• Improve packet bottlenecks that were causing packets to be dropped through the expansion of internal queues and updates to packet forwarding logic.
• Modifications to GDL90 reporting spec to comply with standard values (e.g. vertical rate not available).
• Make aircraft dictionary num aircraft configurable at compile time.
• Fix issue that caused ownship ICAO address to jump around on WiFi GDL90 (wasn't being initialized).
• Improve OTA stability.

ADSBee 1090 Firmware 0.9.0 Release Candidate 16

• Fixes uptime timestamp wrapping issue on sub-GHz radio.
• Fixes compatibility issue with Avare by no longer transmitting ownship unless all ownship fields are being actively filled (would previously transmit zeroed ownship packets, causing the Avare screen to jump to null island).
• Adds AT+ESP32_REBOOT_INFO? command for dumping ESP32's reason for rebooting.
• Enables ESP32 core dump to flash on Debug builds only, with core dump printing upon AT+ESP32_REBOOT_INFO? query. Disabled on release firmware to avoid wearing out flash if we encounter a recurring abort bug.
• Adds AT+ESP32_TRIGGER_ABORT command for testing the reboot info query.
• Fix ESP build warnings and misc build issues.
• Import ESP32 partition and bootloader during build process, not just application binary (CI and local builds).
• Add the ability to build ESP32 for Debug or Release, triggered by Pico firmware build preference.

Note: Artifacts attached are release firmware. Debug firmware must be built from source.
