QCZEK LRS Config Tool Version 1.6

QczekLRSConfigTool_1.6

Please always check if all settings are saved correctly after power cycle!

 

FIRMWARE

Version 1.71 433MHz MASTER ONLY Beta

What’s new/fixed:

only for checking if resync problem (if no telemetry used) is fixed

and SBUS input is supported just {ParSetInt proto 2} 😉

qczek_lrs_hw_6.2_433_master_v1.71_P_CPPM_P_PXX_P_SBUS

 

Version 1.70

What’s new/fixed:

  • RSSI and air speed available in Tower app
  • optimized TX side sync routine
  • fix which, may (or not) prevent 868MHz modules to be burned during quick on/off cycle
  • support for eByte E32/E45 100mW modules (not range tested)

qczek_lrs_v.1.70

 

Version 1.60

What’s new/fixed:

  • optimized resync routine
  • new packet lost based rssi calculation

Please note that you need to use latest configuration tool.

 

qczek_lrs_v.1.60

Version 1.50

What’s new/fixed:

  • RX/TX switching optimization
  • Beta version of race mode – just to check how 500kHz band is working. Using race mode frames are send at 21Hz with full telemetry and up to 35Hz without telemetry.
  • Hardware watchdog restart RX if no synchronization occurs, according to configuration parameter (default 30s)
  • Additional parameter (bit mask) to prevent setting (by 10s button press) fail safe values for selected channels.

Please note that you need to use latest configuration tool.

qczek_lrs_v.1.50

Version 1.40

qczek_lrs_v.1.40

What’s new/fixed:

  • Hardware watch dog used to reset board when any of scheduled tasks takes more then 0.5s
  • Hardware watch dog used to reset slave (RX) board if during fail safe state, no synchronization occurs for 30 seconds. Just in case if RF chip has some problems…
  • SX1278 receiving optimization according to Semtech errata
  • Correction to XJT(PXX) frame reading to avoid using fail safe settings frame as normal channels values
  • Many changes in mavlink tunnelling protocol, to send as much as possible info to Droid Planner like applications. Unfortunately due to flash memory limitation, no way to pass RSSI and relative alt.

Know issues:

  • 868MHz version, not tested for long distances!
  • 915MHz version, not tested at all!
  • DMA serial buffer is not processed correctly in settings mode, so you have to press several times enter or space key

Version 1.30

qczek_lrs_v.1.30

What’s new:

  • Code size optimization
  • Changing sequence of PA and RX/TX switch switching
  • Sending RSSI via telemetry, even without mavlink capable FC connected
  • Experimental support for E44 modules (915MHz)

Know issues:

  • 868MHz version, not tested for long distances!
  • 915MHz version, not tested at all!
  • DMA serial buffer is not processed correctly in settings mode, so you have to press several times enter or space key

Version 1.20

qczek_lrs_v.1.20

What’s new:

  • First 8 channels send in every frame !
  • RF channel number included in payload, for better synchronization, and possibility to use same freqencies for different rf channels
  • 4 instead of 3 bytes of serial data send in every master->slave frame
  • Minor master/slave synchronization bug fixed

Know issues:

  • 868MHz version, not tested in real environment !
  • DMA serial buffer is not processed correctly in settings mode, so you have to press several times enter or space key

Version 1.10 BETA for E45-TTL-1W 868MHz modulese

qczek_lrs_v.1.10_BETA_868MHz

What’s new:

  • E45-TTL-1W (868 MHz band) supported

Know issues:

  • It’s beta version, not tested in real environment !
  • DMA serial buffer is not processed correctly in settings mode, so you have to press several times enter or space key

Version 1.10

qczek_lrs_v.1.10

What’s new:

  • support for SBUS protocol
  • support for lbeep
  • faster re sync after package dropping
  • shorted LED blinks at start up

Version 1.00

qczek_lrs_v.1.00

What’s new:

  • support for PXX (also know as XJT D8 and D16) input protocol (without CRC calculation)
  • adaptive telemetry rate – find out more
  • more secure way to enter settings mode for slave module (RX module). Now you need connect M1 and M2 pins together. It solved reported issue, when RSSI LC filter forces RX always to start in settings mode. Master module (TX module) enters settings mode in old way.
  • RSSI based on SNR or signal strange
  • Due to limited resources (flash memory), a lot of customization parameters and other text/messages are shorter now
  • Solved problems with non responding behavior after saving settings

Know issues:

  • DMA serial buffer is not processed correctly in settings mode, so you have to press several times enter or space key

Version 0.91

  • serial port speed can be set
  • new telemetry mode is available, you can directly connect uBlox GPS and use it.
  • new parameter timeToFS making possible to setup time to fail safe activation
  • single servo mode, first channel value could be output as standard 50Hz servo PPM signal. It make possible to control single servo directly from receiver.
