I'm using MKW01 with Radio Utility firmware. I've correctly routed DIO0/DIO1 to PTC3/PTC4, but when I want to send a packet, the only interrupt generated is the TxFifoLevel related to DIO1. My packet (10 byte length) is splitted in two blocks, but then I never received the PacketSent interrupt on DIO0.
1) Could it be a software problem? If there's a version for pre-production chip, I can test it on Reference Board
2) Does it still works without connections to PTC3 and 4?
