Communication error has occurred due to one of the following problems:
• Communication failure has occurred because no ACK was received despite having re-sent twice. (A
framing error was detected in the hardware at the IOT side.)
• Communication failure has occurred because no ACK was received despite having re-sent twice.
(An overrun error was detected in the hardware at the IOT side.)
• Communication failure has occurred because no ACK was received despite having re-sent twice.
(Receive abort was detected after header authentication at the IOT side.
• This occurs when the NAK that notifies the occurrence of communication failure was received.
(The Sequence No. of the received Message Packet is incorrect.)
• This occurs when the NAK that notifies the occurrence of communication failure was received.
(The Packet No. of the received Message Packet is incorrect.)
• This occurs when the NAK that notifies the occurrence of communication failure was received. (A
parity error was detected in the hardware of the UART.)
• This occurs when the NAK that notifies the occurrence of communication failure was received. (An
overrun error was detected by hardware of the UART.)
• An abnormal parameter was set in the argument of the receiving function, which causes an error.
• IOT Driver initialization failure.
