Is it possible to transmit a PDU1 PGN using the J1939 manager and local device? What if I need to transmit a PGN RQST via 0xEA00 (PGN 59904)? How would I do this P2P (Destination < 0xFF) or broadcast (Destination 0xFF)? I don't think this is possible for any destination type.
I don't think it's possible to receive broadcast PDU1 messages either. For example, an address claim PGN 60928 (0x18EEFF80) is addressed to all nodes (0xFF) and not any specific local device so it will be filtered out.
These are major oversights in the IoDrvJ1939 library to not support every PDU1 RX/TX scenario.
IoDrvJ1939 supported scenario:
1. Receive (RX) PDU1 (P2P) destination-specific (PDU-specific < 255) to local device with matching address

2. Transmit (TX) PDU1 (P2P) global (PDU-specific = 255)
3. Transmit (TX) PDU1 (P2P) destination-specific (PDU-specific < 255)
