I have STM32 microcontroller F4 I want to configure the GPS sensor for getting data, I used CANBUS cable and the protocol is nmea 2000, and communicate with HAL_CAN interrupt. my question is, how can I phrase the data from the sensor (on nmea 2000). I want to get data from PGN 127257, I need to transmit data (PGN 127257) for reading? or only phrase the data, and if phrase how?

thanks a lot!

void HAL_CAN_RxFifo0MsgPendingCallback(CAN_HandleTypeDef *hcan){

HAL_CAN_GetRxMessage(hcan, CAN_RX_FIFO0, &RXheader, an_packet.NemaData);
u32_2b.bytes[0] = an_packet.NemaData[0];
u32_2b.bytes[1] = an_packet.NemaData[1];
u32_2b.bytes[2] = an_packet.NemaData[2];
u32_2b.bytes[3] = an_packet.NemaData[3];
mid1 = u32_2b.data;
mid = (mid1 >> 8) & 0x01ffff;
 if((mid == 126992) || (mid == 127257) || (mid == 127252) || (mid == 129540)) {
     GPS.test1 = 5;
 }

}

an_packet.NemaData = getting data from the sensor.

    u32_2b.bytes[0] = an_packet.NemaData[0];
    u32_2b.bytes[1] = an_packet.NemaData[1];
    u32_2b.bytes[2] = an_packet.NemaData[2];
    u32_2b.bytes[3] = an_packet.NemaData[3];
    mid1 = u32_2b.data;
    mid = (mid1 >> 8) & 0x01ffff;
     if((mid == 126992) || (mid == 127257) || (mid == 127252) || (mid == 129540)) {
         GPS.test1 = 5;
     }

trying to phrase it...
