      Hello all,

      I am doing a project with two Lopy4's, Initially it went well but from last three weeks i am getting an error in receiver side which is shown in the below.
      i have tried updating firmware but no change, Even for simple basic data transmission also getting the error.
      Can any one please suggest me how to solve this issue.

      Thanks in advance.

        Dear @sita,

        you might want to try one of our dragonfly builds [1]. Some have been successful mitigating spurious core panics with it.

        If core panics are still happening, I will be happy to receive respective core dumps from it. If you could share the MicroPython code it would even be better in order to reproduce the problem.

        With kind regards,
        Andreas.

          Hello @andreas,

          Thanks for the immediate response. I have erased the device using [1] and updated the new firmware.
          But now i got another issue;
          I am doing pure LoRa communication (Lopy4 to Lopy4 only). I kept one Lopy4 as transmitter and other as receiver. Transmitter sending data without any problem but receiver is not receiving the data, it is giving message like this

          rx.jpg

          I do not have any idea regarding smart provisioning. Could you please suggest me how to overcome this issue.
          Thanks in advance

            @sita "Smart Provisioning" is done by the Pybytes firmware, which makes the device hard to use if you do not need it. The firmware images provided by @andreas do not have that. You can disable it by placing a file on you device with the name pybytes_config.json, and the content:

            { "pybytes_autostart": false }

              Thanks for response but i am not fully aware of pybytes_config.json. I just placed a file on the device and in that file i have kept { "pybytes_autostart": false }.
              I got response like this(shown in the below image). I am not sure whether it is right or wrong!!!
              Could i get any document or web link related to this issue so that i will do accordingly.

              Thanks in advance

                @sita That's fine now. Pybytes does not start, and the AP should be enabled. If you use Pybytes, then you might set that to true again. I have not documentation about the mechanism. I had to reverse-engineer that method of disabling. Pycom also did not say or write anything about it. It seems very unfriendly to push it's customers into a non-working configuration.

                  @robert-hh Thanks for the information. After adding that pybytes_config.json file also i am not received data,only getting this message(shown in the below fig). My project is mainly focusing on the received data and i have to analyze it. so could you please help me with this problem.

                  Thanks in advance

                    @sita Please check, that:
                    a) you have set both device to the same communication parameters, like frequency, spreading factor, bandwidth
                    b) that you use the right antenna connector
                    c) that you start both device with power-up or hard reset.

                      @robert-hh Thanks for the immediate response.
                      I have checked all the parameters and they are same for both the devices. And i have connected antennas also right way,still i am not reeving any data and getting same problem again (Guru Meditation Error: Core 0 panic'ed) :(

                      one more problem is the below one is not working for factory reset.
                      import os
                      os.mkfs('/flash')

                      one question is , if i downgrade the firmware is there any use ?? if so which version is preferable ?

                        @sita The best method for a factory reset is performing a full flash erase using esptool.py.
                        Using a previous firmware release will get you away from the pybytes stuff. Since the flash use between v1.20.x and the previous ones has changed, a flash erase is useful anytime you cross that version border.

                          Dear @sita,

                          others are observing similar things on the LoPy4, even with the Dragonfly builds [1]. Are there any chances you could share the MicroPython code and respective core dumps you are receiving while running Dragonfly?

                          Regarding

                          Smart Provisioning started in the background.

                          Are you sure you have been running the vanilla Dragonfly build here? It actually looks like a Pybytes variant. Please try again using the vanilla variant.

                          Thanks already and with kind regards,
                          Andreas.

                            Hello @andreas,

                            i have done the procedure according to [1] and vanilla Dragonfly build also done again. Now it is working fine, data also receiving now. :):)

                              Thanks for letting me know. Please tell me if things are still stable after longer runtimes.

                                Hello @andreas,

                                I got an issue again with this Guru meditation error. While sending the data suddenly this error is coming, if i switch off and on the battery data is transferring normally. Because of this discontinuity i am not able to calculate the packet loss. Is there any solution for this ?

                                  Dear @sita,

                                  I got an issue again with this Guru meditation error.

                                  If core panics are still happening, I will be happy to receive respective core dumps from it. If you could share the MicroPython code it would even be better in order to reproduce the problem.

                                  With kind regards,
                                  Andreas.

                                    I'm trying to send loraraw data packets with GPS, timestamp along with a integer( to calculate the packet loss) in them. Once the data is sent, the same will also be stored in the SD card. After no fixed amount of time, the sender module crashes with guru meditation error, but will restart itself to send the data packets. So i'm seeing a break in the integer number, which will restart from 0 after this error. The sender module code that I wrote is as follows:

                                    import machine
import math
import network
import os
import time
import utime
import gc
import socket
import pycom
import ustruct
#from machine import RTC
from machine import SD
from L76GNSS import L76GNSS
from pytrack import Pytrack
from network import LoRa
from math import ceil

sd = SD()
os.mount(sd, '/sd')
os.listdir('/sd')

#time.sleep(2)
gc.enable()

py = Pytrack()
l76 = L76GNSS(py)

lora = LoRa(mode=LoRa.LORA, region=LoRa.EU868, frequency=433000000, power_mode=LoRa.ALWAYS_ON, tx_power=10, bandwidth=LoRa.BW_125KHZ, sf=8, preamble=8, coding_rate=LoRa.CODING_4_8)
# create a raw LoRa socket
s = socket.socket(socket.AF_LORA, socket.SOCK_RAW)


i = 0
while True:
    coord = l76.coordinates()
    gps_datetime = l76.get_datetime()
    lat,lon = coord

    timestamp =('20' + gps_datetime[4][4] + gps_datetime[4][5]+gps_datetime[4][2] + gps_datetime[4][3]+gps_datetime[4][0] + gps_datetime[4][1]+gps_datetime[2][0] + gps_datetime[2][1]+gps_datetime[2][2] + gps_datetime[2][3]+gps_datetime[2][4] + gps_datetime[2][5] )

    #s.setblocking(True)
    value = i
    message = ''+str(lat)+','+str(lon)+','+str(timestamp)+','+str(value)
    pycom.heartbeat(True)
    s.send(message)
    i = i+ 1
    print(message)
    pycom.heartbeat(False)
    pycom.rgbled(0xff00)
    f = open('/sd/A_3001SF8.txt', 'a+')
    f.write(message)
    f.write(' ')
    f.write('\n')
    f.close()

                                    Kindly please have a look into this issue and guide me so i can continue my work to calculate the packet loss etc., Thanks a lot in advance and have a nice day.

                                    Best Regards,
                                    Sita

                                      I am also seeing Guru Meditation Errors with latest firmware v1.20.1.r2 and vanilla releases.
                                      Here's just a few:

                                      Guru Meditation Error: Core 1 panic'ed (Unhandled debug exception)
                                      Guru Meditation Error: Core 0 panic'ed (IllegalInstruction). Exception was unhandled.
                                      Guru Meditation Error: Core 0 panic'ed (IllegalInstruction). Exception was unhandled.

                                      The code makes heavy use of the UARTs and runs flawlessly on desktop.

                                        Dear @sita,

                                        So, it seems to happen while performing lora_join within mods/modlora.c.

                                        // check for the correct lora radio mode
if (lora_obj.stack_mode != E_LORA_STACK_MODE_LORAWAN) {
    nlr_raise(mp_obj_new_exception_msg(&mp_type_OSError, mpexception_os_request_not_possible));
}

                                        I assume this is some synchronization issue wrt. the code is already doing other things.
                                        Maybe waiting for successfully joining the LoRaWAN network helps like outlined within [1] before doing other operations.

                                        Forget about my last words. I believe this is wrong as I've probably used the wrong application.elf file for decoding the core dump -- see next post(s).

                                        I just recognized you are using pure LoRa instead of LoRaWAN....

                                        @sita said in Guru Meditation Error:

                                        lora = LoRa(mode=LoRa.LORA, region=LoRa.EU868, frequency=433000000, power_mode=LoRa.ALWAYS_ON, tx_power=10, bandwidth=LoRa.BW_125KHZ, sf=8, preamble=8, coding_rate=LoRa.CODING_4_8)

                                        ... so who should be actually invoking lora_join anyway ;].

                                        With kind regards,
                                        Andreas.

                                        P.S.: To be safe that the core dump decoding gives us the correct results: Are you using lopy4-vanilla-dragonfly-onewire or lopy4-vanilla-dragonfly-onewire-i2s?

                                          What baffles me is that [1] shows:

                                          // check for the correct lora radio mode
if (lora_obj.stack_mode != E_LORA_STACK_MODE_LORAWAN) {
    nlr_raise(mp_obj_new_exception_msg(&mp_type_OSError, mpexception_os_request_not_possible));
}

                                          Drawing a conclusion from that, might it be that lora_join is not advisable when doing raw LoRa as outlined within your code

                                            I have to admit I didn't keep track of the application.elf files coming out of my builds which are required to properly decode the core dumps. May I humbly ask you to try again using LoPy4-1.20.1.r3-0.8.0-vanilla-squirrel.tar.gz?
