Thank you for information and for your hints! In this case i want to check the status byte from RN2483 every hour. Bit number 4 shows the Join status (‘0’ – network not joined, ‘1’ – network joined). But here i got another strange problem - if i implement this in my code, suddenly on microcontroller side the RX-Interrupt will not be triggered anymore. And this has to do (so i am sure) with the RN2483 sleep mode, because it works when the module is not in sleep mode. But for this problem i posted a separate threat here: > [@UART communication problems with RN2483A](https://www.thethingsnetwork.org/forum/t/uart-communication-problems-with-rn2483a/34239): > > Hi, i am using the RN2483A module (firmware vers. 1.0.5) with an STM32 microcontroller. Until now all works fine with the communication over UART interface, but now I want to implement a status check with command mac get status, the UART-RX interface of my microcontroller doesn’t work anymore or I would better say that the UART-RX interrupt is not triggered. The cause of the problem must somehow be related to the sleep/wakeup of the RN2483A module because it works perfectly when I don’t put th… --- _[View the full topic](https://www.thethingsnetwork.org/forum/t/how-to-handle-an-automatic-re-join-process/34183)._
