Hello,
I want to use the RAK7391 (WIth a Raspberry CM4 and a RAK5146). The framework used for the nodes is Meshtastic on a RAK4630. So far, the nodes are communicating correctly. My goal is to receive the same LoRa packets exchanged by the nodes on the gateway.
I am actually testing the whole setting with the SX1303 HAL library, specifically, the test_loragw_hal_rx. So far, I am not receiving all packets, or rather receiving rarely some packets, I get the following output for example:
===== sx1302 HAL RX test =====

My question is: What can possibly be the problem?
I would also appreciate it if there is already a library that can do LoRa packets ‘sniffing’ correctly.
Thank you so much in advance
