CC2652R7: Logging the data of the peripheral device getting detected at central device.

Hello Issac,

Is there some sample code for doing the same. I am new to this and an example would help me to grasp the concept faster. 

Also, will the method I mentioned in question work with CCS-theia since it is based on visual studio code ?

Thanks,

Garvit

Hi Isaac,

I have imported the Log project in the CCS but I am still not able to configure it to work with the simple central project. Can you guide me how to combine these 2 projects?

Thanks,

Garvit

Hi Issac,

Thanks for sharing the detailed process. I am getting error as shown in image below

I have added the predefined symbol as suggested

and the search path I gave is as follows

I also tried adding the path of log folder under properties > Build > Arm Compiler> Include Options

Thanks,

Garvit

Hello Garvit, 

I'm unable to replicate the error you are receiving. To summarize the steps, I am taking:

1) I added the ti_log_Log_ENABLE to the Predefined Symbols section within the project Properties.

2) I add the two log modules to the SysConfig, located at SysConfig->Logging->Log Modules. Additionally, I added the same Log Level Configurations to the Global Parameters within the SysConfig->Logging->Log Modules -> Global Parameters.

3) Added the Includes into main.c and simple_peripheral.c.

4) Added the log_printf into the main.c file, within the main function. 

5) Debugged and started running the project. Opened Runtime Object View (ROV), navigated to LogSinkBuf, and refreshed the feed to see the log entries. 

(I also added the file search path, and the include option you provided, the log feature worked with these included and without). 

Could you please provide me with the steps you took leading up to the error? Additionally, can you provide me the SDK version you are using? 

Thanks, 

Isaac

Hello Garvit, 

The file below is my working log example for the simple_peripheral project. This is on SDK 7.10. All the log function does for this project is output "Hello World!" onto the log. 

5672.simple_peripheral_CC26X2R1_LAUNCHXL_tirtos7_ticlang.zip

Thanks,

Hello Issac, 

I am unable to decode the reason for the error - fatal error: 'ti/log/Log.h' file not found. I am still receiving the same error after repeating all the steps as suggested.

Another thing I want to confirm is, in step 2 the log module are added in the log.syscfg so do we need to link it to simple_peripheral.syscfg file in some way because I don't see any log module in it.

Is there any other way to include the log.h header file to the project ?

I am working with ccs version 12.2.0.00009 and sdk version 7.10. Since the simple peripheral project attached is for different development board, it is not working with the CC2652R7 boards I have.

Thanks,

Garvit

Hello Garvit, 

The logging feature started being supported on CCS 12.3. Can you update to the newest CCS version and then attempt using the logging feature? 

Thanks, 

Isaac

Hello Isaac,

I am getting following error after updating CCS.

Thanks,

Garvit

Hello Garvit, 

Can you double check the name of the log module in SysConfig matches the name of the log module in the Log_printf functions? 

 If this doesn't work, can you reply with pictures of everything you changed in SysConfig, your programs, and the properties of the project?

Thanks, 

Isaac

Hello Issac,

I have checked the name for log modules - 

The is still persisting. 

SysConfig and properties changes - 

I am working with the simple peripheral project example for CC2652R7 and I haven't made any other changes in the scripts than the ones suggested for activating the logging.

Thanks,

Garvit

Hello Garvit, 

I am looking into the problem on the 7.10 SDK. I will get back to you sometime tomorrow. Sorry for the inconvenience. 

Thanks, 

Isaac

Hello Garvit, 

Just for additional clarification are you on SDK version 7.10.01.24, or SDK version 7.10.00.98? Let me know!

Thanks, 

Isaac

Hello Issac,

Thanks for all the efforts you are making. I am working with 7.10.00.98 SDK version.

Regards,

Garvit

Hello Issac,

The project you shared is working with the logging activity but I am still not able to figure out the reason why it was not working earlier. I have tried implementing the steps in the simple_central code but I am still receiving same error.

Did you implement it in a different way for this device? Also, I don't see any additional path added in the "File search path" option in the simple peripheral project you shared.

Thanks,

Garvit 

Hello Issac, 

Here is the project I was working on.

simple_central_LP_CC2652R7_tirtos7_ticlang.zip

Thanks,

Garvit

Hello Garvit, 

Thanks for sending me your project. Let me know if the project I sent works for you!

Thanks, 

Isaac

Hello Issac,

First of all thanks a lot for all the help you have provided till now.

The central project you sent is able to log the hello world but I am struggling to modify the syntax to capture the device address and RSSI values for the discovered devices in central project.

I have added following piece of code under  "case SC_EVT_ADV_REPORT:" in "static void SimpleCentral_processAppMsg(scEvt_t *pMsg)" function of central project - 

{
GapScan_Evt_AdvRpt_t* pAdvRpt = (GapScan_Evt_AdvRpt_t*) (pMsg->pData);

// === SOLUTION [Print scan results] ===
//Print scan response data or advertising data
if (pAdvRpt->evtType &= ADV_RPT_EVT_TYPE_SCAN_RSP)
{
Display_print1(dispHandle, 4, 0, "ScanResponseAddr: %s",
Util_convertBdAddr2Str(pAdvRpt->addr));
Display_print1(dispHandle, 5, 0, "ScanResponseData: %s",
Util_convertBytes2Str(pAdvRpt->pData, pAdvRpt->dataLen));
}
else
{
Display_print2(dispHandle, 6, 0, "Advertising Addr: %s RSSI: %d",
Util_convertBdAddr2Str(pAdvRpt->addr), pAdvRpt->rssi);

 Log_printf(LogModule_App1, Log_INFO, "RSSI = %d Address = %s ",pAdvRpt->rssi,Util_convertBdAddr2Str(pAdvRpt->addr));

Display_print1(dispHandle, 7, 0, "Advertising Data: %s",
Util_convertBytes2Str(pAdvRpt->pData, pAdvRpt->dataLen));

}

The code builds without error but the values logged in ROV are random and not equal to the ones displayed on terminal

Thanks,

Garvit

Hello Issac,

Waiting for your response.

Thanks,

Garvit

Hello Garvit, 

Sorry for the delay. The log driver does not currently allow for strings to be outputted by using %d and/or %s. For outputting large strings, please reference the Log_Buf feature. Let me know if you have any questions. 

Thanks, 

Isaac

Hello Issac,

I am unable to locate the Log_Buf feature you are talking about. The link you shared takes to the BLE5 stack user guide and I tried finding the logging related information in various sub headings but I am not able to locate it. Can you mention the heading and sub heading as well for locating the information?

Thanks,

Garvit

Hello Garvit, 

Sorry about that. Here is an updated link for the API. Again, let me know if you have any questions. 

TI Utilities API: Log Interface

Thanks, 

Isaac

Hello Issac,

I am still not able to log the rssi values and address of device using the Log_Buf . I tried adding the following piece of code -

int8_t rssiValues = {pAdvRpt->rssi};
Log_buf(LogModule_App1, Log_DEBUG, "The contents of bufferToLog are: ",rssiValues, sizeof(rssiValues));

This syntax is also not able to log the RSSI values.

Also, you mentioned - " The log driver does not currently allow for strings to be outputted by using %d and/or %s." but rssi is of int8_t data type. Why does the code Log_printf(LogModule_App1, Log_INFO, "RSSI = %d",pAdvRpt->rssi); doesn't work for logging the rssi values?.

Thanks,

Garvit

Hi Garvit,

I hope you are doing well. I will be taking over this thread going forward. My apologies if I ask a question that has been asked previously in this thread as I am still catching up on this thread. Lets take a step back and check if the Log_printf() works with any variable. Could you ty to do something along the lines of the code shown below and let me know if you can see the output or not? I would like to make sure the printf function is working as expected before moving onto the RSSI functionality.

int myVar = 5;
Log_printf(LogModule_App1, Log_DEBUG, "The contents of myVar is %d ",myVar);

Best Regards,

Jan

Hi Jan,

Log_printf is working as expected. I can see the output as 5. Issue is I am not able to print the elements of structure "pAdvRpt"  like RSSI and device address in the "SimpleCentral_processAppMsg"  function of simple central code.

Thanks,

Garvit

Sure, I can do that.
