I am facing an issue where a device successfully registers with the Chirpstack and sends its data.
I am also able to send data to the device, but after the first message is sent, the device gets locked. Subsequently, any data I try to send goes into a queue and remains there until the driver sends any packet. Once the driver sends a packet, the queue is released, and everything works correctly. However, if I restart the driver, the issue returns.
The end device is class C.
This problem occurs on Chirpstack v4.3, while it worked correctly on v3.
