Hi @rajarahul96,
Please update to the latest firmware! If you are running an earlier version, you may be running into a bug that was present in an earlier version!
You can check which version of the firmware you are using, with these commands:
import os os.uname() -
Thanks. It is working.

@rajarahul96 hello, I have the save problem. Could you please tell me which firmware did you change ? The pymakr version, or the lopy firmware version ? It would help me a lot. Thanks!

@bilou7 I would try doing it on the LoPy first as there is probably nothing to loose in any case. (backup your the files on the lopy, first just in case).
Just be sure all ends are speaking the same LoRa specifications.
Example: If you have a device provisioned on a server somewhere at 1.0.0 and the firmware happens to upgrade you to 1.0.2 -
I am seeing a similar issue with my FiPy device (when using NB-IOT communications).
I suspect the problem has something to do with the sockets code and not specifically LoRa.
I am running the latest version of software on my FiPy.
