Firmware Version 3.10 for ASR 6601 devices with TCXO
Whis is the firmware for new ASR6601 based devices. In two flavours, the old UART is for direct wires soldering, the new UART pin layout is for a small board designed by me. Please note that initial firmware loading should be done using old UART pins.
Firmware Version 3.10 for ASR 6601 devices
What’s new/fixed:
- master (TX) supported
- many small problems fixed
- fixed max RF power issue (please upload updated files from 08.01.2023)
Know problems:
- Limited support, only CRSF, and others…
Firmware Version 3.01 for ASR 6601 devices
What’s new/fixed:
- fixed problems with locking serial TX DMA channel – timeout workaround
- fixed telemetry ground speed calculation
Know problems:
- Limited support, only RX, CRSF, and others…
Firmware Version 3.00 for ASR 6601 devices
What’s new/fixed:
- New platform, find out more there
Know problems:
- Limited support, only RX, CRSF, and others…
- Possible problems with sending CRSF frames to FC. Always use watch dog timer. In case of problems, just switch off your transmitter for longer then watch dog time set.
Firmware Version 2.11
What’s new/fixed:
- Instead of using RF automatic gain control, now it’s fixed and set to max, which makes RSSI/SNR more stable
- Completely redesigned frame lost/resync routine, to fix long 1-2s signal lost, which has been reported
Know problems:
- For unknown reasons it’s better to set higher (like 56700 bps) serial port speed for RX module connected to FC. Maybe it’s not Qczek LRS bug, and lower speeds are not enough for high bandwidth mavlink stream.
Firmware Version 2.10
What’s new/fixed:
- Fixed s-port generation.
- Fixed re sync in race mode.
- Channels from 4-16 may be filtered to make value changes more smooth. There is new parameter 0 – no filtering, 15 – max filtering. Please note that it small delay (depending on filtering strength.
Know problems:
- For unknown reasons it’s better to set higher (like 56700 bps) serial port speed for RX module connected to FC. Maybe it’s not Qczek LRS bug, and lower speeds are not enough for high bandwidth mavlink stream.
Firmware Version 2.00
What’s new:
- Only SBUS protocol supported on TX/Master side.
- Shorter radio frame, lowering time on air and overal delay.
- Channels 1 – 8 values encoded in 10 bits (prev 11bits).
- Channels 9-16 encoded in 5 bits.
- Race mode switched by RC channel.
- Telemetry protocol switched from raw data strim to selected protocol by RC channel.
- High telemetry rate switched by RC channel.
- Default serial port speed is 4800 bps. It’s used for configuration.
- For TX/Master only 4800 bps is supported.
- several small improvments and bug fixes.
