Lora 2483 sleeping for extra 10 seconds ,uplink communication

Hello everybody
im really happy to be one of your members in this forum

i have problem with lora devices, when i try to send data its works fine for the 10 first messages then my device become busy and it takes from 5-10 mins to be ready to send again
this the message that im getting:“The device is busy. Sleeping for 10 extra seconds.”
i have searched for solutions but i found that the problem is about the power consumption…

do you have any solution for that ? thanks in advance
its urgent for my school project


I think it’s just a duty cycle “problem”, you can’t occupy the band more than 1% of the time. may be you have a function disabling the duty cycle.
