esp32 PacketError problem on receiver #6

Closed promistrio closed 4 years ago

promistrio commented 4 years ago

Hello! The same problem like closed issues on ESP32 (basic example for esp32). I made sure the transmitter was working. Data from HackRF: image An interesting point was noticed. The message is sent, but it doesn't get broadcast. Check the blue line.

I think the error is not related to esp32

promistrio commented 4 years ago

Sorry, you opened the topic while I was typing this one. I use http://www.ebyte.com/en/product-view-news.aspx?id=286 and pins that you define in settings.h

StuartsProjects commented 4 years ago

I think the error is not related to esp32

Can you elaborate, its not clear what you mean ?

When reporting an issue with the library, its really helpful to me if I know exactly what hardware you are using, in this case which microcontroller and which LoRa module ?

promistrio commented 4 years ago

this module (sx1280) http://www.ebyte.com/en/product-view-news.aspx?id=286 dev board based on ESP32-WROOM-32 module. image

Can you elaborate, its not clear what you mean ?

The module passed the libs tests, so the SPI connection works. It is strange why the message is detected when it arrives, but its length is 0

promistrio commented 4 years ago

Another interesting point. The receiver always detects the sent message. But not always on HackRF.

SDRs do not always pick up the very short packets, so that the SDR does not see it is not direct evidence that it was not sent.

With no packet received (or transmitted) a correctly wired ESP32 module will display an RXtimeout message.

The library and examples work correctly on an ESP32 bare module, but then that is an actual ESP32 WROOM with no additional hardware. Its possible there is a pin conflict with the ESP32 board you are using. These boards are often referred to as ESP32s, buy they can have additional hardware added that causes problems.

Receiver display rxtimeout, but receive and show error every incorrect packet.

May be I will try to connect wires to module without devboard pin hardware.

And i will try another library.

promistrio commented 4 years ago

Can you tell me what problems are taking place if there are spi, and GPIO. SPI works in this case. May be I can to fix this. Why does the transmitter work?

StuartsProjects commented 4 years ago

Receiver display rxtimeout, but receive and show error every incorrect packet.

Can you show me the serial monitor output, that includes both timeout and incorrect packet. Do not reduce or omit from the printout the sequence is important.

update: _RXDonePin is working.

The problem starts with reading the buffer: readCommand(RADIO_GET_RXBUFFERSTATUS, buffer, 2); It returns 0x0, 0x0, so the variables _RXPacketL and RXstart are equal to zero

update 2: How does it works? If I change mosi miso pin in settings, it still works.

I think that problem in spi. readCommand always return 0x0

update 3:

I show all buffers from readCommand

RXstart: 0

readCommand(): 0x00 00 00 00 00 

readCommand(): 0x00 00 00 00 00 

readCommand(): 0x80 00

  1. How to check whether the payload changes in the message on the transmitter? I swapped two modules and the radio transmission still works. May be the problem is not with SPI.
  2. Tomorrow I can test on a bluepill stm32f103 and with arduino library
  3. I still question the poor quality of the esp32 devboard. SPI transmission works during the test, works for transmission, but does not work during radio reception. GPIO pins function without complaints.

The examples work reliably on a bare bones ESP32, so I suspect your issue is that your ESP32 board has some additional haedware that is interfering with the pins being used.

Cannot comment on whether the examples will work on an Bluepill, not tested.

promistrio commented 4 years ago

Could you send your circuit for esp32?

I'm sure the transmitter is sending data, because the height on the SDR depends on the size of the message. For example, there are two simultaneous transmitters with different message lengths. https://youtu.be/YRTEGxApDOM

Soon I will try to run the Mbed library on stm32 on a receiver

Hello!

BluePill works without problems! It's really ESP32 board problem. I suggest adding an entry about this to the ReadMe.

StuartsProjects commented 4 years ago

There already is a note about potential problems ESP32s in the readme.

There is no generic problem with the code not working on ESP32, bu there may well be an issue with your particular ESP32 or how it is wired.

There are too many ESP32 board varients for it to be practical to test them all, there are over 60 supported by the Arduino IDE.
