Hey Jason, I am all over a non custom solution.
I am in Texas, so 915.
The mDot is using the mDot_lora_example_tnn_connect.Do you mean this from GitHub:
https://github.com/Lora-net/packet_forwarder/tree/master/basic_pkt_fwd
If I used the global_conf.json do I need to change anything.
edit: this config is for 868 mhz. So there has to be a bunch of changes.
or is it as easy as search and replace:
“freq”: 868500000,
for
“freq”: 915??????????????????,https://github.com/Lora-net/packet_forwarder/blob/master/basic_pkt_fwd/global_conf.json
I am pretty green at this config stuff.
Here is the mDot code:
#include “mbed.h”
#include “mDot.h”
#include “MTSLog.h”
#include <string>
#include <vector>
#include <algorithm>
// these options must match the settings on your Conduit
// TTN Keys

static const uint8_t data_session_key_array[] = {0x2B, 0x7E, 0x15, 0x16, 0x28, 0xAE, 0xD2, 0xA6, 0xAB, 0xF7, 0x15, 0x88, 0x09, 0xCF, 0x4F, 0x3C};
// uncomment the following lines and edit their values to match your configuration

osDelay(std::max((uint32_t)1000, (uint32_t)dot->getNextTxMs()));
}// format data for sending to the gateway
for (std::string::iterator it = data_str.begin(); it != data_str.end(); it++)
data.push_back((uint8_t) *it);printf(“Device ID {“);
std::vector<uint8_t> deviceId;
deviceId = dot->getDeviceId();
for (std::vector<uint8_t>::iterator it = deviceId.begin() ; it != deviceId.end(); ++it) {
printf(“0x%2.2X”,*it );
printf(“%s”, it != (deviceId.end() -1 ) ? “, ” : ” ” );
}
printf(“}\r\n”);while (true) {
// send the data to the gateway
if ((ret = dot->send(data)) != mDot::MDOT_OK) {
logError(“failed to send”, ret, mDot::getReturnCodeString(ret).c_str());
} else {
logInfo(“successfully sent data to gateway”);
}// in the 868 (EU) frequency band, we need to wait until another channel is available before transmitting again
osDelay(std::max((uint32_t)10000, (uint32_t)dot->getNextTxMs()));
}return 0;
}Ok, I got those coordinated and it looks like the concentrator is getting 100%.
I don’t see any messages with my gateway eui at ttn.
https://thethingsnetwork.org/api/v0/nodes/I do see my gateway at ttn.
https://thethingsnetwork.org/api/v0/gateways/What log can I look in to see where the conduit failing?
Ideas?
Thank you.
