dragino-1's Issues

Errors in log file

I am have some code that is using your library and is reading Atlas Scientific sensors installed on a raspberry pi every 15 minutes.

I am seeing error in the error log and have listed this below. The error seems to result in the data packet not being transmitted to my lorawan gateway When I view the logs on my own lorawan gateway and on the TTN console I am seeing quite of lot of missing fcnt counts and thought this error might be the cause of it.

OTAA Connection Issue

Dear @BNNorman,

I am experiencing difficulties in establishing an OTAA connection using the library. Below are the logs captured during my attempt to connect with test.py :

...

It appears that despite receiving a JOIN_ACCEPT packet, the device does not seem to be properly registered, as indicated by the repeated 'devaddr' error.

Could you please advise if there are specific configurations or steps I might have missed? Any help in resolving this issue would be greatly appreciated.

Thank you for your time and assistance.

Issue with Missing Method in Dragino Library

Dear @BNNorman,

I hope this message finds you well. I am currently working with the Dragino library on a Raspberry Pi project, and I have encountered this error that seems to stem from a missing method within the library.

Here is the error message:

Traceback (most recent call last):
  File "/home/pi/dragino-1/./test.py", line 27, in <module>
    D.join()
  File "/home/pi/dragino-1/dragino/dragino.py", line 493, in join
    self.configureRadio(radioSettings.JOIN)
  File "/home/pi/dragino-1/dragino/dragino.py", line 185, in configureRadio
    self.set_spreading_factor(sf)
  File "/home/pi/dragino-1/dragino/SX127x/LoRa.py", line 663, in set_spreading_factor
    self.set_low_data_rate()
AttributeError: 'Dragino' object has no attribute 'set_low_data_rate'

The issue arises when trying to configure the radio settings using the set_spreading_factor method, which in turn attempts to call set_low_data_rate. However, it appears that the set_low_data_rate method does not exist in the Dragino class.

Could you please provide guidance on whether there is a fix or a workaround for this issue? Alternatively, if there is an updated version of the library that addresses this, could you point me in the right direction?

Thank you for your assistance.

Best regards,

Impossible to Set a Fixed SF

Hi, Am I the only one unable to set a fixed SF to 7? If I set it into the Toml file (ADR = 5), then the node can't join the TTN network, while if I keep it at ADR = 3, then it joins the network correctly but with SF9. I need to use SF7, ADR is not enabled in TTN but the problem persist, where am I wrong?
Thank you for your work
