How can i read and write in internal flash during run time?

You have to enable OSAL_SNV=1 in BLE Stack project and then you can use osal_snv_read and osal_snv_write to read/write internal Flash.

thank you sir,
sir, where I can receive event data in observer file after scanning ?

You can do it in SimpleBLEObserver_processRoleEvent

event data not ok?

0 Vijendra Goyal over 9 years ago in reply to Vijendra Goyal

Intellectual 715 points

event data means ......other device advertise data or something else....i received garbage data in pEvent data location

0 YiKai Chen over 9 years ago in reply to Vijendra Goyal

Guru 735695 points

Do you check pEvent in case GAP_DEVICE_DISCOVERY_EVENT?

0 Vijendra Goyal over 9 years ago in reply to YiKai Chen

Intellectual 715 points

no,I check pEvent in GAP_DEVICE_DATA_INFO
in GAP_DEVICE_DISCOVERY_EVENT there is no data...

0 YiKai Chen over 9 years ago in reply to Vijendra Goyal

Guru 735695 points

How do you check it? Set a breakpoint?

0 Vijendra Goyal over 9 years ago in reply to YiKai Chen

Intellectual 715 points

Yes I set a break point in SimpleBLEPeripheralObserver_processRoleEvent()

at case GAP_DEVICE_DISCOVERY_EVENT:

If you check devList, do you see anything?

I want to configure BLE MAC Address through UART. How can i do this?

0 Christin Lee over 9 years ago in reply to Vijendra Goyal

TI__Guru 57665 points

Then you need to use simple_np project to accomplish this.
Or you can add UART driver into your project and then once you receive the msg from UART, you can call HCI_EXT_SetBDADDR(). However, you can only change the mac address when the device is in idle.

0 YiKai Chen over 9 years ago in reply to Vijendra Goyal

Guru 735695 points

I don't see there is such interface. Why do you want to configure BLE MAC address?

0 Vijendra Goyal over 9 years ago in reply to YiKai Chen

Intellectual 715 points

I want to add secondary BLE MAC through UART.

0 Vijendra Goyal over 9 years ago in reply to Vijendra Goyal

Intellectual 715 points

with the secondary MAC i also want send name of BLE device.So all BLE devices will show different names.

Hello Yk Chen

At present my BLE device name is showing SPP BLE SERVER .It is available in scan response data i can change it.But i want to send device new through UART.How it possible?

0 YiKai Chen over 9 years ago in reply to Vijendra Goyal

I don't see HCI command to do it so you might need to implement your own serial command to set attDeviceName[] and call "GGS_SetParameter(GGS_DEVICE_NAME_ATT, GAP_DEVICE_NAME_LEN, (void*)attDeviceName);" to set it.

How can i save received data in internal flash of cc2650.(Data Received by UART and BLE both )

0 YiKai Chen over 9 years ago in reply to Vijendra Goyal

Guru 735695 points

You can enable OSAL_SNV=1 in the Stack project and use API osal_snv_write to write data to internal flash of CC2650.

0 Vijendra Goyal over 9 years ago in reply to YiKai Chen

I have enable OSAL_SNV=1 in the stack project.set Preprocessor OSAL_SNV=1 and call osal_snv_write and write data of sdiRx buffer but not working.Please help

uint16 SDIRxBuf_Read(uint16 len)
{
uint16 partialLen = 0;

// Need to make two reads due to wrap around of circular buffer
if ((len + RxBufTail) > SDI_TL_BUF_SIZE)
{
partialLen = SDI_TL_BUF_SIZE - RxBufTail;
SDITL_readTL(&RxBuf[RxBufTail],partialLen);
len -= partialLen;
RxBufTail = 0;
}

// Read remainder of data from Transport Layer
SDITL_readTL(&RxBuf[RxBufTail],len);

if((RxBuf[0]==0x41)&&(RxBuf[1]==0x54)&&(RxBuf[2]==0x49)&&(RxBuf[3]==0x2B)) ///added vijendra
{
VOID osal_snv_write(BLE_MAC_ADD_CONFIG, 6,RxBuf);
}

SDIRXBUF_RXTAIL_INC(len);

// Return len to original size
len += partialLen;

return len;
}

#define BLE_MAC_ADD_CONFIG 0x81

0 YiKai Chen over 9 years ago in reply to Vijendra Goyal

Guru 735695 points

I add the following code to simple_peripheral and run it on my CC2650DK. Everything works fine.

uint8 RxBuf[16];
uint8 TxBuf[16];

RxBuf[0]=0x12;
RxBuf[1]=0x34;
RxBuf[2]=0x56;
RxBuf[3]=0x12;
RxBuf[4]=0x34;
RxBuf[5]=0x56;
osal_snv_write(0x81, 6,RxBuf);
osal_snv_read(0x81, 6,TxBuf);

yes if we set default values then it works but I want to send different value in running module.Like data received by uart.

0 Vijendra Goyal over 9 years ago in reply to Vijendra Goyal

Intellectual 715 points

Means different data send by mobile app to BLE or By PC serial port to UART of BLE Module

0 YiKai Chen over 9 years ago in reply to Vijendra Goyal

Guru 735695 points

I see no difference on this and don't think it won't work when you write flash with data come from UART of BLE module.

0 Vijendra Goyal over 9 years ago in reply to YiKai Chen

Intellectual 715 points

but not working if i send buffer through serial port it received but not write.It not hitting on break point set at
return NVOCOP_writeItem(nv_id, len, pBuf); in stack project.

0 YiKai Chen over 9 years ago in reply to Vijendra Goyal

Guru 735695 points

I couldn't understand your latest description. Can you elaborate?

0 Vijendra Goyal over 9 years ago in reply to YiKai Chen

Intellectual 715 points

when i send data through UART it recieved in sdi_rxbuf.c file at SDITL_readTL(&RxBuf[RxBufTail],len);

I want to write this buffer(RxBuf) in internal flash.

0 YiKai Chen over 9 years ago in reply to Vijendra Goyal

Guru 735695 points

I cannot do osal snv write in sdi_rxbuf.c too. osal_snv_write/osal_snv_read always returns INVALIDPARAMETER(0x02). It seems to be related to ICALL problem but I cannot find a solution for now.

0 Vijendra Goyal over 9 years ago in reply to YiKai Chen

Intellectual 715 points

thanks,
Is there any other option to write UART buffer into internal flash?

0 Robert Chen over 9 years ago in reply to Vijendra Goyal

Firstly, why is there a "VOID" in front of the function call?

VOID osal_snv_write(BLE_MAC_ADD_CONFIG, 6,RxBuf);

Secondly, you have to know that "it takes a lot of time" to write flash. During writing, CPU should be blocked. Task-switching is not permitted. So, your UART driver will be blocked, too. You have to check the implementation of "STL".

Personally, I don't use osal_snv_write() since I don't know how it is implemented. I call the low-level APIs directly and make sure interrupts are disabled while writing flash.

How can i update scan Response data in run time.

How can i Update Scan Response data in non connected mode .(I am receiving data on UART of CC2650 every minute i want to update this data in scan response data).

0 YiKai Chen over 9 years ago in reply to Vijendra Goyal

Guru 735695 points

Can you specify which example you are using and elaborate what you mean you want to update this data in scan response data?

0 Vijendra Goyal over 9 years ago in reply to YiKai Chen

Intellectual 715 points

i am using spp ble server.
i want to add some bytes(variable) in scan response data in run as below
memcpy(&scanRspData[21],&var_bUff,10);
GAPRole_SetParameter(GAPROLE_SCAN_RSP_DATA, sizeof(scanRspData),
scanRspData);
but case GAPROLE_SCAN_RSP_DATA: return 0x02 for this , data also not updated.

can i update scan or advertise data in run time?
