Downlink Data Location and Receive Window Time

[meakash]

I am using a grasshopper board to send data to TTN whenever i press a button. The uplink and downlink packets gets incremented everytime i send an uplink packet.

I want to know what is being send as downlink, where it is stored, how to read that downlink message and i know how to use Node Red with Arduino based end nodes to send specific downlink packets, is there any way in which i can send a custom downlink?

Please bear with me as i am just starting with LoRaWAN and grasshopper board.

See the LoRaWAN_Callbacks.ino example:

if (LoRaWAN.parsePacket())
{
    uint32_t size;
    uint8_t data[256];

    size = LoRaWAN.read(&data[0], sizeof(data));

    if (size)
    {
        data[size] = '\0';

        Serial.print(", PORT: ");
        Serial.print(LoRaWAN.remotePort());
        Serial.print(", DATA: \"");
        Serial.print((const char*)&data[0]);
        Serial.println("\"");
    }
}

Thank you so much sir, this works for me.

int setReceiveDelay(unsigned int delay);

Sir, i would like to play with delays for a development work (although not correct to do it). RX2 delay can be increased easily, what about RX1, how to increase it?

[kriswiner]

No idea.
