      1. Hello! Is it possible for version 2.11 to change MAVLINK 1.0 to 2.0?? MAVLINK 2.0 has been in INAV flight controller firmware for a long time.

    1. Hi. I flashed 2.11 on old E32 modules

      TX was ok but after flashing the RX (R433A mavlink) the module was bricked.
      I flashed another module with RX firmware but after that it was bricked too…
      Communication error both with serial and ST8 programmer (unable to read the chip or reflash)..

      Anyone with the same problems?

      1. Hard to say,
        The modules are now in many different flavours (different MCU?), even if marked the same like the old one…

        1. Thank you Kris
          I saw that another uses said here he had the same problem.
          Error message like swim disconnect

          Is there a way to solve?

        2. Solved.

          to deblock the module, it needs to be powered and after a few seconds plugged with rst and swim pins.

          so i flashed with 1.19 and all is ok now


  1. Hi qczec ! Thank you for your efforts and enthusiasm . Have some problems with
    T868B_P_SBUS_T_SPORT_V2.11.s19 firmware . Module is E32 868T20D . I am not able get into config mode after flashing . Config tool is not working and if I tried to open putty session at 4800 and send {ParGetAll} I am geting no response . Sure I put M1 to ground before .

    If I reflash same module with R868B_T_MAVLINK_P_CPPM_P_SBUS_V2.11.s19 and bridge M0 and M1 config mode works fine both in configurator tool and putty session .

    if I reflash same modeule with old T868B_P_SBUS_T_SPORT_V1.92.s19 and put M1 to ground – config works without any problems . Any idea ?

  2. I found what is wrong – changed pin assigment since 2.10 on TX module . There is no much information about it . so actual pin assigment in 2.10 is

    module RX — SBUS input
    module TX – RX telemetry and config at 4800
    module AUX – TX telemetry and config at 4800

    1. Hi qczec! How do you comment this? Is it true? I had some similar problem, but I could connect when AUX pulled to the ground. Also I can’t setup finally, I don’t know the reason. But what about RX and TX did you swap them?

      1. Why do you pull AUX to the gnd?
        For tx module, AUX works as serial RX, because hardware RX is used for sbus input….

    2. Thank You! I was desperate trying to connect to TX module with >1.92 firmware

  3. Hi Qczek, Any chance that you share the processor type and pin connections that you use in your code, If the processor can be sourced then we can use any SX1278 module with an external processort board (blue pill perhaps) with your software..

    1. No problem, i can share it with you, and it was already shared.
      I can also compile version for any pin assignment, but please note that it is stm8 not stm32 architecture.

  4. Hi Qczek! Is it possible to use a 1-W module (like a E45-TTL-1W 868 MHz) as a transmitter, and a 100-mW (like a E32-868T20S) as a receiver? Will they be compatible and work?

  5. Hello,
    Very good job. Does it support the frequency of 915m? Does E22-900M30S firmware support it?

  6. Hi dear colegs
    I have program E32 868 T30S and E32868 T30d by 2.1 and 2.11 resultat zero not working (no any signal from module)
    but with 1.92 all working not so good as i wish but working- not posible tuned telemetry
    and also befoore it i have proramed E32 915 T 30D by 2.1 it is working exlelent with telemetry
    May be problem with new moduls ? (maybe сhines peaple changed same things in the modules)
    Please help me
    Looking forward to your advice

    1. Good afternoon, Konstantin! I faced the same problem! The E32 868T30D module refuses to work with firmware higher than 2.0. I think we are not the only happy owners of these boards. I think the problem is that the new firmware lacks some kind of protocol needed to start the HF part of the module. Dear Qczek, please help in solving this problem, except for you no one does the firmware. Qczek Pimp my copter)))

  7. Hello. Thanks for your hard work. I have a question. For the new version 2.11 there is no setup program to download. What program can I use to configure? If you can, give instructions on how to set it up. I have a 915MHz lore. Thanks.

  8. Hello! After researching a little bit and getting myself E32 433T30D pair I wanted to use flash QCZEK Lrs to them and test it.
    Howewer, I was wondering if it is possible to use QLRS only as mavlink brige? (like standart 433 SiK radio)
    For example: 5.8 ghz for video, 2.4 ghz for rc and 433 ghz for telemetry.
    The goal is to get the mavlink direct control over the model from Mission Planner like with Dragonlink and still have separate frequency for the rc… more frequencies … more bandwidth.
    Is it possible?

      1. Thanks for the response! Even that it is not possible to make it work the way i want to, I want to try it. My current problem is that i’m unable to flash E32 433T30D with the provided fw using STlinkV2. I’ve tried all of the possible solutions, even checked if pcb pinout is correct, but no luck. It always errors with “SWIM not connected or blocked” message (can not set write permissions on the chip either). Anyone has any suggestion? Help is much appreciated!

        1. Tbm tenho um módulo desse e estou querendo inicia a minha montagem do qczek mas será q irei ter o mesmo problema??

        2. Acabei de verificar e o meu E32 433t30d utiliza stm8, eu comprei em 2015 no ali, então vou comessar e tentar montar o meu qczek

  9. Hello, I am also interested in this regard, it would be great to expand the functionality of this system. Make a module only for telemetry, but leave it possible to choose the frequencies. Thanks.

  10. Hello Konstantin. On Ali Express they sell 433MHz modules with a power of 2 W. The processor is different.
    AX5243 433 МГц 33dBm UART DIP IoT Uhf.
    Maybe you can make it so that there is a program for this module. Thank you for your work.

  11. Good day! Thanks for all your efforts! Can we have a hope that the new E32-433T30D with cortex m0 (10337-V1.0) will be supported one day? There is almost no chance to get 433 modules with ST8 processor for now!

    1. Hi,
      Currently I work on asr MCU implementation, to make it fuck… cheap 🙂
      It would be easy to migrate to m0 MCU i think.

  12. Hello! I ask for your help!
    Given: Reptile S800 and DIY flying wing. Everywhere is Qczek LRS 2.11
    Problem: Constant disconnections on a DIY flying wing!
    On the reptile everything is OK. I turn off the reptile and turn on the wing. The remote control swears “very low signal”, gaps appear.
    Sensor data:
    RSSI 04B1 -42dB
    SNR 02B2 3dB
    RSSI F101 87

    RSSI -42dB
    SNR 6dB
    RSSI 1dB

    I re-flashed the receiver – it did not help. I made one more receiver – the same trouble!
    Modules E32868T20S

  13. Good day! I have a problem with 2.11 with 1w modules on 915MHz. It’s losing packets constantly. If I put 15ms refresh rate on the app settings it’s better, but not good. Have you any suggestions on what can be wrong there?

    The video demonstration is available at the link below.

    Thank you for your efforts!

  14. By any chance, do you have internal schematic/pcb for E32 868 T30? I’m interested to code myself just need ST – Semtech wiring and exact STM8 version. Thanks

    1. I’m working on ASR6601 newest SOC implementation, but i hard due to debugging problems…
      Nice to know, i haven’t seen this project before.

  15. Hi Qczek! Thank you for the great solution and your reliable support!
    I’ve spotted new 170Mhz modules at Ali. They have same hardware as 433MHz modules. Would it be possible to compile a firmware for new modules?
    Thank you!
    Kind regards,

    1. Hi,
      Sure we can try, give me a link to mentioned module. We need to check if it’s based on the same MCU.

        1. ok,
          Do you already have it on your desk?
          I’m not sure if it shares same MCU.
          So if you have it you can try to load RX firmware first and try to comunicate using config soft.

          we can coontinue discusion via email krzysztof dot kuczek at gmail dot com

          1. Do not have it yet, just ordered a pair today…
            There is a picture at the product description section showing SX1278 and 8L151G chips…
            OK, will drop a message by e-mail.

  16. Hello, Kris! Do you think it makes sense to try to establish the production of modules based on stm8? I understand that my question is naive, but nevertheless, I would like you to appreciate the complexity of this task.

  17. Hi. I have receiver E32 915T20s. I am connected same as schematic from this sait. But I can’t upload firmware… When i check gain on reset I see low gait alwys… Can you help me? Thank you for replay.

  18. Hello QCZEK! Is it possible for version 2.11 to change MAVLINK 1.0 to 2.0?? MAVLINK 2.0 has been in INAV flight controller firmware for a long time.

  19. Sorry. I don’t know where to ask.
    I have a new ebyte E32 30DB type 10498 v 1.1 module.
    On the back whe have VCGD pins
    The G is the ground. The V is not connected with Vin pin.
    I assumed that CD are Swim and reset but it doesn’t work

    What can I do to find swim and reset pins?


  20. Hello! I would like to ask a question 🙂 I have a few sx1278 LoRa boards, but without serial, it only has SPI interface. Can I just flash QCZEK LRS to some STM8 board and connect it by SPI ? Would it work? Thanks!
