Confirmation Checklist

• The package is maintained in this repository.
• I understand that issues related to the base OpenWrt repository or LuCI repository will be closed.
• I am reporting an issue for OpenWrt, not an unsupported fork.

Start with the sx1302_hal package and reproduce the hang using the EU.USB JSON configuration and /etc/init.lora_pkt_fw start. Observe logread -f while checking the main task, uplink thread, and lgw_receive mutex behavior. Done means identifying and resolving the condition that leaves lgw_receive blocked and prevents the main task from progressing.
