LBT: (ERROR) packet is NOT allowed to be transmitted

mcoracin commented 7 months ago

Hello, What commands and config are you using exactly ? When LBT is enabled, it is allowed to transmit only on the channels described in the LBT config. If a downlink occurs on another channel, il will be rejected.
