# Deactivate/Delete modem configuration file

This sample app demonstrates how to deactivate and delete modem configuration file.

1. Get the ConfigFactory instance

auto &configFactory = telux::config::ConfigFactory::getInstance();

2. Get ModemConfigManager instance and Wait for sub system initialization

std::promise<telux::common::ServiceStatus> prom{};
    modemConfigManager_ = configFactory.getModemConfigManager(
         [&prom](telux::common::ServiceStatus status) {
             prom.set_value(status);
    });
    
    if (!modemConfigManager_) {
        std::cout << "Failed to get modem config Manager" << std::endl;
        return;
    }
    
    //  Check if modem config subsystem is ready
    //  If  modem config subsystem is not ready, wait for it to be ready
    telux::common::ServiceStatus managerStatus = modemConfigManager_->getServiceStatus();
    if (managerStatus != telux::common::ServiceStatus::SERVICE_AVAILABLE) {
        std::cout << "\nModem config subsystem is not ready, Please wait ..." << std::endl;
        managerStatus = prom.get_future().get();
    }
    
    // Exit the application, if SDK is unable to initialize modem config subsystems
    if (managerStatus != telux::common::ServiceStatus::SERVICE_AVAILABLE) {
        std::cout << "ERROR - Unable to initialize subSystem" << std::endl;
        return;
    }
    Copy to clipboard

3. Deactivate modem configuration

std::promise<bool> p;
    telux::common::Status status = modemConfigManager_->deactivateConfig(configType_,
            slotId_,[&p](telux::common::ErrorCode error) {
             if (error == telux::common::ErrorCode::SUCCESS) {
                 p.set_value(true);
             } else {
                 std::cout << "Failed to deactivate config" << std::endl;
                 p.set_value(false);
             }
    });
    
    if (status == telux::common::Status::SUCCESS) {
        std::cout << "Deactivate Request sent" << std::endl;
    } else {
        std::cout << "Deactivate Request failed" << std::endl;
    }
    
    if (p.get_future().get()) {
        std::cout << "deactivate config succeeded." << std::endl;
    }
    Copy to clipboard

4. Request configuration list from modem’s storage

// configList_ is member variable to store config list.
    std::promise<bool> p;
    telux::common::Status status = modemConfigManager_->requestConfigList(
         [&p, this](std::vector<telux::config::ConfigInfo> configList,
                                         telux::common::ErrorCode errCode) {
         if (errCode == telux::common::ErrorCode::SUCCESS) {
             configList_ = configList;
             p.set_value(true);
         } else {
             std::cout << "Failed to get config list" << std::endl;
             p.set_value(false);
         }
    });
    
    if (status == telux::common::Status::SUCCESS) {
        std::cout << "Get Config List Request sent" << std::endl;
    } else {
        std::cout << "Get Config List Request failed" << std::endl;
    }
    
    if (p.get_future().get()) {
        std::cout << "Config List Updated !!" << std::endl;
    }
    Copy to clipboard

5. Delete modem configuration file from modem’s storage

std::promise<bool> p;
    // configNo denotes the index of config file in config list
    configId = configList_[configNo].id;
    
    telux::common::Status status = modemConfigManager_->deleteConfig(configType_,
           configId, [&p](telux::common::ErrorCode error) {
             if (error == telux::common::ErrorCode::SUCCESS) {
                 p.set_value(true);
             } else {
                 std::cout << "Failed to delete config" << std::endl;
                 p.set_value(false);
             }
    });
    
    if (status == telux::common::Status::SUCCESS) {
        std::cout << "Delete Request sent successfully" << std::endl;
    } else {
        std::cout << "Delete Request failed" << std::endl;
    }
    if (p.get_future().get()) {
        std::cout << "Delete config succeeded." << std::endl;
    }
