Jason, is there a way to set the frame counter on the gateway?

[Joshua Lilly]

So I may have stumbled across an answer, it looks like the issue is from the AES-128 keys, since I am using ABP. When I unplug the seeeduino I noticed that the issue happens, so on the gateway it looks like I will have to delete the device and re-add it along with adding a session to be able to send and receive the data.

Not sure if that is the best answer so someone please correct me 😛

One other interesting thing is that when I issue lora-query -n I receive:
Dev Addr Dev EUI Class Joined Seq Num Up Down 1st 2nd Dropped RSSI min max avg SNR min max avg PER%

Thanks for the info Jason! Sorry for the slow response I just got back around to trying to get this to work.

Jason, I will update the firmware. That is also the hardware I am trying to get working. I am currently using one of the example sketches, which I have modified slightly, since I am in the US using the 915 band. I also looked up the channels to use through another tutorial and added those, which strike me as one possible issue. There is also an example ABP session join, but I am still not able to get it working correctly. Apologies for the basic nature of the question, I am very new to these technologies

Here is the code I am working with for OTA:

#include <LoRaWan.h>

unsigned char data[10] = {1, 2, 3, 4, 5, 6, 7, 8, 9, 0xA,};
char buffer[256];

void setup(void)
{
SerialUSB.begin(115200);
while (!SerialUSB);

lora.init();

memset(buffer, 0, 256);
lora.getVersion(buffer, 256, 1);
SerialUSB.print(buffer);

memset(buffer, 0, 256);
lora.getId(buffer, 256, 1);
SerialUSB.print(buffer);

lora.setKey(“2B7E151628AED2A6ABF7158809CF4F3C”, “2B7E151628AED2A6ABF7158809CF4F3C”, “2B7E151628AED2A6ABF7158809CF4F3C”);

lora.setDeciveMode(LWOTAA);
lora.setDataRate(DR0, US915);

lora.setChannel(0, 903.9);
lora.setChannel(1, 904.1);
lora.setChannel(2, 904.3);
lora.setChannel(3, 904.5);
lora.setChannel(4, 904.7);
lora.setChannel(5, 904.9);
lora.setChannel(6, 905.1);
lora.setChannel(7, 905.3);

lora.setReceiceWindowFirst(0, 903.9);
lora.setReceiceWindowSecond(904.1, DR3);

lora.setDutyCycle(false);
lora.setJoinDutyCycle(false);

lora.setPower(14);

while (!lora.setOTAAJoin(JOIN))
{
SerialUSB.println(“trying join”);
}
SerialUSB.println(“Join success”);
}

void loop(void)
{
bool result = false;

result = lora.transferPacket(“Hello World!”, 10);
//result = lora.transferPacket(data, 10, 10);

if (result)
{
short length;
short rssi;

memset(buffer, 0, 256);
length = lora.receivePacket(buffer, 256, &rssi);

if (length)
{
SerialUSB.print(“Length is: “);
SerialUSB.println(length);
SerialUSB.print(“RSSI is: “);
SerialUSB.println(rssi);
SerialUSB.print(“Data is: “);
for (unsigned char i = 0; i < length; i ++)
{
SerialUSB.print(“0x”);
SerialUSB.print(buffer[i], HEX);
SerialUSB.print(” “);
}
SerialUSB.println();
}
}
}

Here is the code I was trying for ABP, note this one is a little different since I am trying to use the US915HYBRID as opposed to the US915:

#include <LoRaWan.h>

unsigned char data[10] = {1, 2, 3, 4, 5, 6, 7, 8, 9, 0xA,};
char buffer[256];

void setup(void)
{
SerialUSB.begin(115200);
while(!SerialUSB);

lora.init();

memset(buffer, 0, 256);
lora.getVersion(buffer, 256, 1);
SerialUSB.print(buffer);

memset(buffer, 0, 256);
lora.getId(buffer, 256, 1);
SerialUSB.print(buffer);

lora.setKey(“2B7E151628AED2A6ABF7158809CF4F3C”, “2B7E151628AED2A6ABF7158809CF4F3C”, “2B7E151628AED2A6ABF7158809CF4F3C”);

lora.setDeciveMode(LWABP);
lora.setDataRate(DR0, US915HYBRID);

lora.setChannel(0, 903.9);
lora.setChannel(1, 904.1);
lora.setChannel(2, 904.3);
lora.setChannel(3, 904.5);
lora.setChannel(4, 904.7);
lora.setChannel(5, 904.9);
lora.setChannel(6, 905.1);
lora.setChannel(7, 905.3);

lora.setReceiceWindowFirst(0, 903.9);
lora.setReceiceWindowSecond(904.1, DR3);

lora.setDutyCycle(false);
lora.setJoinDutyCycle(false);

lora.setPower(14);
}

void loop(void)
{
bool result = false;

result = lora.transferPacket(“Hello World!”, 10);
//result = lora.transferPacket(data, 10, 10);

if(result)
{
short length;
short rssi;

memset(buffer, 0, 256);
length = lora.receivePacket(buffer, 256, &rssi);

if(length)
{
SerialUSB.print(“Length is: “);
SerialUSB.println(length);
SerialUSB.print(“RSSI is: “);
SerialUSB.println(rssi);
SerialUSB.print(“Data is: “);
for(unsigned char i = 0; i < length; i ++)
{
SerialUSB.print(“0x”);
SerialUSB.print(buffer[i], HEX);
SerialUSB.print(” “);
}
SerialUSB.println();
}
}
}

Thank you for your assistance.
