Hello Rajender,

[quote user=""]so please help me to send this data packet to another thread.[/quote]

You have to make usage of a pointer pointing towards your struct.

 msg_t msgSendPacket, *msgSendPacketPtr = &msgSendPacket;
   //Fill the Packet from UART
   
    /* prepare to send message through Mailbox*/
    mailBoxMsg.info = sizeof(&msgSendPacket);
    mailBoxMsg.size = sizeof(&msgSendPacket);
    mailBoxMsg.tx_data = msgSendPacketPtr;
    mailBoxMsg.tx_block.data = NULL;
    mailBoxMsg.tx_target_thread = tid_myThread;
    k_mbox_async_put(&mailBoxMsgMailBox, &mailBoxMsg, NULL);//NULL means no semphore used
    
    k_poll_signal_raise(&myThreadSignal, dataSig);

During reception, a pointer pointing towards a struct of the same type will fill it with the respective data.

struct k_mbox_msg recv_msg;
msg_t msgRecvPacket, *msgRecvPacketPtr = &msgRecvPacket;

...

/* retrieve message data and delete the message */
k_mbox_data_get(&recv_msg, msgRecvPacketPtr);

I hope this solves your issue!

Regards,

Markus

Hello Rajender,

I have to dive a little into this topic and make myself familiar with the API usage. I will come back to you as soon as possible.

Regards,

Markus
