Mike,
Here’s the `main.cpp’ file. It’s the LoRa Connect Example code here:
https://developer.mbed.org/teams/MultiTech/code/mDot_LoRa_Connect_Example/#include "mbed.h" #include "mDot.h" #include "MTSLog.h" #include <string> #include <vector> #include <algorithm> // these options must match the settings on your Conduit // uncomment the following lines and edit their values to match your configuration static std::string config_network_name = "oeacnetw"; static std::string config_network_pass = "oeacnetw"; static uint8_t config_frequency_sub_band = 7; int main() { int32_t ret; mDot* dot; std::vector<uint8_t> data; std::string data_str = "hello!"; // get a mDot handle dot = mDot::getInstance(); // print library version information logInfo("version: %s", dot->getId().c_str()); //******************************************* // configuration //******************************************* // reset to default config so we know what state we're in dot->resetConfig(); dot->setLogLevel(mts::MTSLog::INFO_LEVEL); // set up the mDot with our network information: frequency sub band, network name, and network password // these can all be saved in NVM so they don't need to be set every time - see mDot::saveConfig() // frequency sub band is only applicable in the 915 (US) frequency band // if using a MultiTech Conduit gateway, use the same sub band as your Conduit (1-8) - the mDot will use the 8 channels in that sub band // if using a gateway that supports all 64 channels, use sub band 0 - the mDot will use all 64 channels logInfo("setting frequency sub band"); if ((ret = dot->setFrequencySubBand(config_frequency_sub_band)) != mDot::MDOT_OK) { logError("failed to set frequency sub band %d:%s", ret, mDot::getReturnCodeString(ret).c_str()); } logInfo("setting network name"); if ((ret = dot->setNetworkName(config_network_name)) != mDot::MDOT_OK) { logError("failed to set network name %d:%s", ret, mDot::getReturnCodeString(ret).c_str()); } logInfo("setting network password"); if ((ret = dot->setNetworkPassphrase(config_network_pass)) != mDot::MDOT_OK) { logError("failed to set network password %d:%s", ret, mDot::getReturnCodeString(ret).c_str()); } // a higher spreading factor allows for longer range but lower throughput // in the 915 (US) frequency band, spreading factors 7 - 10 are available // in the 868 (EU) frequency band, spreading factors 7 - 12 are available logInfo("setting TX spreading factor"); if ((ret = dot->setTxDataRate(mDot::SF_10)) != mDot::MDOT_OK) { logError("failed to set TX datarate %d:%s", ret, mDot::getReturnCodeString(ret).c_str()); } // request receive confirmation of packets from the gateway logInfo("enabling ACKs"); if ((ret = dot->setAck(1)) != mDot::MDOT_OK) { logError("failed to enable ACKs %d:%s", ret, mDot::getReturnCodeString(ret).c_str()); } // save this configuration to the mDot's NVM logInfo("saving config"); if (! dot->saveConfig()) { logError("failed to save configuration"); } //******************************************* // end of configuration //******************************************* // attempt to join the network logInfo("joining network"); while ((ret = dot->joinNetwork()) != mDot::MDOT_OK) { logError("failed to join network %d:%s", ret, mDot::getReturnCodeString(ret).c_str()); // in the 868 (EU) frequency band, we need to wait until another channel is available before transmitting again 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); 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)5000, (uint32_t)dot->getNextTxMs())); } return 0; }Thanks,
