LoRaWan - Raspberry Pi 3B error -6 on method LoRaWANNode::sendReceive() #1037

Closed SocioPJ closed 5 months ago

SocioPJ commented 5 months ago

Hi!

Im using Raspberry Pi 3B to transmit LoRaWAN messages but im getting the error -6 on method sendReceive(). The module im using is the SX1272.

Pinout: NSS pin: 8 DIO0 pin: 17 DIO1 pin: 13 RST pin: 4

The following code is: 

#include <RadioLib.h>
#include "PiHal.h"
#include <string>
#include <stdio.h>

PiHal* hal = new PiHal(1);

SX1272 radio = new Module(hal, 8, 17, 4, 13);

LoRaWANNode node(&radio, &US915, 2);

uint32_t devAddr = 0x2******3;

uint64_t devEUI = 0x2**************3;

uint8_t nwkKey[] = { 0x2B, 0xXX, 0xXX, 0xXX, 0xXX, 0xXX, 0xXX, 0xXX, 0xXX, 0xXX, 0xXX, 0xXX, 0xXX, 0xXX, 0x3C };

uint8_t appKey[] = { 0x2B, 0xXX, 0xXX, 0xXX, 0xXX, 0xXX, 0xXX, 0xXX, 0xXX, 0xXX, 0xXX, 0xXX, 0xXX, 0xXX, 0x3C };

int beginRadio(SX1272 radio){
  int state = radio.begin();
  if(state == RADIOLIB_ERR_NONE){
    printf("[Radio Begin]...ok!\n");
    return (state);
  } else {
    printf("[Radio Begin]...error: %i\n",state);
    return (-1);
  }
}

int beginABPLora(){
  int state = node.beginABP(devAddr, nwkKey, appKey);
  if(state >= RADIOLIB_ERR_NONE){
    printf("[LoRa ABP Begin]...ok!\n");
    return(state);
  } else{
    printf("[LoRa ABP Begin]...error: %i\n",state);
    return (-1);
  }
}
int main(){
  printf("[Radio]...ok!\n");
  printf("[LoRa Node]...ok!\n");

  int state = beginRadio(radio);
  state = beginABPLora();

  // node.setADR(true);
  // node.setDutyCycle(true, 1250);
  // node.setDwellTime(true, 1000);

  uint8_t count = 0;
  while(true){
    const char *strUp = "hello!";
    uint8_t strDown[256];
    size_t lenDown = 0;
    uint8_t port = 10;
    int16_t state = node.sendReceive(strUp, port, strDown, &lenDown);
    // int16_t state = node.uplink(strUp, port);
    if(state == RADIOLIB_ERR_NONE){
      printf("[LoRa sendReceive]...ok!\n");
      printf("[LoRaWAN] Data:\t\t");
      size_t dataDownLength = sizeof(strDown) / sizeof(strDown[0]);

      if(dataDownLength > 0){
        printf("%s",strDown);
      } else {
        printf("<MAC commands only>");
      }
    } else{
      printf("[LoRa sendReceive]...error: %i\n",state);
      return (-1);
    }

    uint32_t minimunDelay = 60000;
    uint32_t interval = node.timeUntilUplink();
    uint32_t delayMs = std::max(interval,minimunDelay);
    hal->delay(delayMs);
  }
  return(0);
}

The error im getting:

[Radio]...ok!
[LoRa Node]...ok!
[Radio Begin]...ok!
[LoRa ABP Begin]...ok!
[LoRa sendReceive]...error: -6

Please enable the RADIOLIB_DEBUG flag and post the output you get of one complete uplink, including integrated timestamps from your terminal. I cannot help you if the log timestamps are missing.

Error -6 for sendReceive is all about the timings, which is why @StevenCellist said:

OK, so there are some things we'll need to check out, but it's not clear if there is an issue with the uplink or you are just getting the normal message that says there wasn't a downlink that has previously been tagged as an error but is actually the expected result for the majority of uplinks.

Does the uplink arrive on the console, which LNS are you using, have you looked up the error code & does it make sense to you in the context of LoRaWAN?

SocioPJ commented 5 months ago

First i though that the transmission is not arriving to the gateway and that's the reason it's not receiving the downlink, so i put a gateway on my desk and still not working. But then i check GQRX software to see if there is any uplink signal on 860 MHZ frequency (the lowest to this module and less signal traffic) and there is not.

StevenCellist commented 5 months ago

Yeah so I've been looking at your code and RadioLib's Pi support in general, and figured that the problem is the thing that struck me the first: your beginRadio(SX1272 radio) function should use pass-by-reference instead of pass-by-value, or in other words: it needs to use a pointer: beginRadio(SX1272 &radio). And subsequently, calls to radio methods in that function need to use -> instead of ., i.e. radio->begin(). But I expect you get the gist of it.

By the way - it also appears you registered your device as LoRaWAN v1.0.4, or you forgot to put in the other two keys. I highly, and I cannot stress it enough, really recommend using LoRaWAN v1.1 instead. LoRaWAN v1.0.4 is not very much supported by RadioLib, especially for ABP. Your device will likely not work on v1.0.4.

Ok, by next week i'll change to OTAA and i say what happended. Tks :)

That as well, but LW 1.1, NOT v1.0.4 ...

StevenCellist commented 5 months ago

@SocioPJ do you have an update on this? Any luck with your Pi adventures (with LW v1.1 & OTAA)?

SocioPJ commented 5 months ago

Hi, srry for late response. So basically the network server that I use don't support LW 1.1 so I have to continue with LW1.0.4. I also discovery that my gateways doesn't send a downlink message when received a uplink, and that is the reason I receive the error -6 (my guess). I changed the LoRaWAN method to .uplink() and I was able to send one message but in the following messages I receive error -1108. I can't show the log right now since I am not with my pc. By wednesday i'll update with the log.

Although the first message was send successfully, the gateway didn't received the signal (I captured the signal on GQRX).

1.0.4 is really not supported, and that means you can't use Helium. You will have to use something other than RadioLib if you want to use Helium.

No, that is not the issue; the issue is in your code unfortunately, as I mentioned (you need to use a pointer to the radio in the beginRadio function).

I changed the LoRaWAN method to .uplink() and I was able to send one message but in the following messages I receive error -1108

That is by design: LoRaWAN requires you to listen to potential downlinks; you cannot just skip a downlink!

Hi, i have some news,

Last week i bought the SX1276 to make new tests since I was not sure if the SX1272 module was ok. The signals are much better now and I was able to caught some payloads on my Network Server!

NetworkServerLogs

I remake the code to something more simple just to test:

#include <RadioLib.h>
#include "PiHal.h"
#include <string>
#include <stdio.h>

PiHal* hal = new PiHal(1);

SX1276 radio = new Module(hal, 8, 17, 4, 13);

LoRaWANNode node(&radio, &AU915, 2);

uint32_t devAddr = 0x2******3;
uint8_t nwkKey[]  = { 0x2B, 0x**, 0x**, 0x**, 0x**, 0x**, 0x**, 0x**,0x**, 0x**, 0x**, 0x**, 0x**, 0x**, 0x**, 0x3C };
uint8_t appKey[]  = { 0x2B, 0x**, 0x**, 0x**, 0x**, 0x**, 0x**, 0x**,0x**, 0x**, 0x**, 0x**, 0x**, 0x**, 0x**, 0x3C };

 int main(int argc, char** argv)
 {
  int state  = 0;

  state = radio.begin();
  if(state == RADIOLIB_ERR_NONE)
  {
    printf("[Radio Begin]...ok!\n");
  } 
  else 
  {
    printf("[Radio Begin]...error: %i\n",state);
  }

 state = node.beginABP(devAddr, nwkKey, appKey);
  if(state == RADIOLIB_ERR_NONE){
    printf("[Radio ABP]...ok!\n");

  } else {
    printf("[Radio ABP]...error: %i\n",state);
  }

  uint64_t devaddr  = node.getDevAddr();
  printf("[LoRaWAN] DevAddr: %llu",devaddr);

  while(true)
  {
    printf("Sending LoRa packet ...");
    state = node.uplink("hello",100);
    if (state == RADIOLIB_ERR_NONE)
    {
      printf("send!\n");
      node.restore();
    }else{
      printf("failed, code %i\n", state);
      return(-1);
    }

  hal->delay(1000);
  }
}

I also did some changes on LoRaWANBands.cpp to just use three specifics frequencies (915.2, 915.4 and 915.6 MHz) :

};

Despite that, I encountered some trouble with the second message and subsequent ones. Every second message onward, I receive error code -1108. Here is my debug log:

Closing as OP unwilling to conform to given feedback, and instead bends universe against the law and intentionally breaking functionality.

HeadBoffin commented 5 months ago

There's no point looking confused - making changes to code & settings that are known to work against an untested LNS using the wrong version to get them going on your own platform is somewhat counter-intuitive. You need to find the reason it doesn't work compared to a working setup, compare & contrast. Almost universally the TTN forum never recommends using a Pi as a device unless it is using a RAK811 (a popular HAT) or other AT based modem due to timing issues. And radical changes to the channel plan for a country have all sorts of consequences.

SocioPJ commented 5 months ago

I apologize for not being clear in all aspects. The LNS and gateway that I use have some modifications and are private. I'm not using public LNS. I wasn't the one who determined these changes, it was my boss at a job he did previously and he asked me to continue with these changes. Therefore, it was necessary to make this adaptation to Australian frequencies. After making this adaptation, I was able to receive data from LoRa in my LNS. I wasn't ignoring the feedback, but there are certain things I need to follow, like continue using ABP and LoRa v1.0.4. Regarding the code, I had redone it based on the examples for Raspberry. I stopped using the sendReceive() method because my gateway does NOT send a downlink in response, so I thought it makes more sense to use uplink(). I understand that using the Pi is not recommended, but it has certain functionality that is necessary for my project. Anyway, I started studying this a month ago, so I still don't know some LoRa concepts. If possible, I'll accept help with the errors I'm having, if not, thank you for everything :)

HeadBoffin commented 5 months ago

RadioLib is developed by volunteers. There are no restrictions on using it for commercial projects AFAIK and if you were using TTS, LW1.1 and suitable known good tested MCU platform we'd not be here.

But you are using a RPi with an unsupported LW version on an LNS that could have any number of changes that we aren't aware of for a commercial project.

Phrases like "because my gateway does NOT send a downlink in response," indicate that you have some way to go before you understand what LW is all about and LW is not a system that falls neatly in to place even with known setups.

It's not appropriate to expect free assistance to help solve what can only be described as a disaster that's potentially not finished unfolding. And FWIW, it's not fair on you for someone to expect you to learn new tech AND use a non-standard setup.

You may want to hunt out a Pi implementation of LMIC which is only 1.0.3. Or there is a python version, not sure what version that supports. Or commission someone to sort this out but I'd suspect they will ask a lot of WHY questions (like why change the LNS, why use ABP, why use a Pi as a device) and then recommend reverting to standard kit to get the project done.

Good luck!
