1. Preparation

1.1 Demo program recurrence steps

• Purchase T95 development board
• Download the SDK and guidance documents of T95
• Compile new firmware
• Merge Source code
• Firmware burning
• Program effect demonstration

1.2 How to get T95's SDK

Sample_Applications can get SDK by purchasing T95 development kit Link : Thundercomm T95

1.3 How to build and debug T95's hardware firmware

This article summarizes the compilation and debugging steps. For detailed steps, please refer to the document 《Thundercomm+TurboX+T95+Platform+IoT+SDK+User+Guide.pdf》

• Python

Python is used to compile the sample in SDK, please install Python 2.7.9 or more advanced.

• LLVM 4.0 compiler

LLVM is used to compile the sample in SDK

• Build app firework

SDK\Sample_Applications\io9205_led> .\build_dam_sample_app.bat

• Push app with QFLOG

SDK> python.exe .\QFLOG\src\QFLOGPackage\QFLOG.py -p <COMPORT> PUSH -f <FilePath>

• Enable log view

SDK> python.exe .\QFLOG\src\QFLOGPackage\QFLOG.py -p <COMPORT> VIEW_LOGS

        qapi_DSS_Net_Evt_t      evt,           /* Event identifier */
        qapi_DSS_Evt_Payload_t *payload_ptr)   /* Associated event information */
{
	// ...
	// Call t95_coap_init in "QAPI_DSS_EVT_NET_IS_CONN_E"
    if (evt == QAPI_DSS_EVT_NET_IS_CONN_E)
    {
		// ...
		ret = t95_coap_init();
		if (ret != 0)
		{
			LOG_ERROR("*****t95_coap_init failed!***** ret = %d", ret);
		}

	}
	// ...
}

2.2 Button message business logic in business cycle

File path :

Sample_Applications\io9205_track\src\demo\track_demo_module.c

Function name：

dam_app_routine

Logic implementation：

void dam_app_routine(void)
{
	// ...
	while (1)
	{
		// ...
		//  Call upload_dev_info at "while (1) "
        ret = upload_dev_info();
		if (ret == 0)
		{
			LOG_INFO("upload_dev_info succeed\n");
			qapi_Timer_Sleep(3, QAPI_TIMER_UNIT_SEC, true);
		}
		else
		{
			LOG_INFO("upload_dev_info failed\n");
			qapi_Timer_Sleep(3, QAPI_TIMER_UNIT_SEC, true);
		}
		LOG_INFO("upload_dev_info end\n");
		// ...
	}
	// ...
}

2.3 Realization of message reporting function in network module

File path :

Sample_Applications\io9205_track\src\demo\io9205_net.c

Function name：

upload_dev_info

Logic implementation：

int upload_dev_info(void)
{
    LOG_INFO("=====upload_dev_info start.=====\n");
    LOG_INFO("======================= upload_dev_info sos msg =======================\n");
    #if 1
    LOG_INFO("upload_dev_info alarm msg\n");
    if (QAPI_ERROR == app_coap_send_tracker_alarm_message_func())
    {
        LOG_INFO("upload_dev_info alarm msg error\n");
        return -1;
    }
    LOG_INFO("upload_dev_info loc msg\n");
    if (QAPI_ERROR == app_coap_send_tracker_loc_message_func())
    {
        LOG_INFO("upload_dev_info loc msg error\n");
        return -1;
    }
    #endif
    LOG_INFO("======================= upload_dev_info sos msg end! =======================\n");
    return 0;
}

2.4 Add COAP module to the project

• 1. Import io9205_coap_control.h io9205_coap_control.c File path.
• 2. Add a reference to io9205_coap_control.h in io9205_net.h and track_demo_module.h

3. Joint Debugging

Flash fireware for T95, turn on TurboX T95, start joint debugging:

• 1. Wait 1-2 minutes for SIM card network registration after powered up
• 2. Click the button2 on T95
• 3. Log in to the website from server
• 4. Check the reported data based on the "user guide"
