Hello sir,

will you tell me one thing that can we use direct read write functions in esb_prx function?

and also tell me that the fds example you had told that is working in sdk 11.0.0.i had tried that example its working fine in sdk 11.0.0. then i have tried by adding fds library in my main code i.e in ble_app_uart in sdk 12.2.0 added all fds function calls i.e write ,fds_read() on my ble_app_uart i had added the fds code same as added in the proximity example. compiled my project with 0 errors.but i noticed that in my fds code the fds_init() function executes continuously.it will not going on the next loop. i am not understanding why it is happening.

so my main question is that can we use fds in only sdk 11.0.0. or it can be used in sdk 12.2.0.

Thank you

Pallavi

FILE_ID AND REC_KEY is not fixed, and you can change them. From the infocenter:

Record keys should be in the range 0x0001 - 0xBFFF. The value 0x0000 is reserved by the system. The values from 0xC000 to 0xFFFF are reserved for use by the Peer Manager module and can only be used in applications that do not include Peer Manager.

File IDs should be in the range 0x0000 - 0xBFFF. The value 0xFFFF is used by the system. The values from 0xC000 to 0xFFFE are reserved for use by the Peer Manager module and can only be used in applications that do not include Peer Manager.

You can use e.g. a different REC_KEY or FILE_ID to group/split your data up.

sir i am trying with that example but i want to store my data in perticular format.i.e there are 15 arrays i want to store and data around 150 bytes but there is only one method given i.e to werite on fds.i want to ask is it possible to store no of different arrays in the fds and there are seperated by 0x36 0x36 data .but the fds code i had seen writes data on flash in one stroke. please tell me how can i store no of arrays one after another.and in between that how can i add 0x36 0x36 data because i also want to read that data.is it

#define FILE_ID 0x1111

#define REC_KEY 0x2222

changable or it is fixed.

i want to store these array with 0x36,0x36 in between two different array and read these array how it is possible.

See this github page. Click the "Clone or download" button, and click download ZIP. Put the example you want in your SDK folder.

sir i have seen in sdk in nRF5_SDK_11.0.0_89a8197 (1)\examples\peripheral folder there is no fds example .i havent seen fds example in sdk 11.0.0 .and also in nRF5_SDK_11.0.0_89a8197 (1)\examples\ble_peripheral this folder.there is no fds example code is given. there is fds only in library nRF5_SDK_11.0.0_89a8197 (1)\components\libraries.but i am looking for code so that first i can understand the fds concept.the github link you have shown in that there is no downloading option.so will you tell me where i can get the code for fds so that i can test it according to my requirement seperately then i wll add this to my main code.

Thank you, Pallavi

Thank you sir.first i will take a look on the fds code.then i have to understand its concept i.e how to store data on fds. after that i have to impliment all my functions on that.if there is any problem then ill take you help. but for now thank you for your ans.

Thank you,

Pallavi

I took a look at your code, and the problem seems to be that you are accessing flash directly (erase/write) when the SoftDevice is enabled (in your write_AC_data() function ).

If you use the SoftDevice, direct access to flash is restricted. We suggest you to use the fds library. fds is a simple file system, you don't have to worry about the address you store the variable or how you back up data when erasing a page. Fds is used in our ble example in the SDK, we have a small example here(for SDK-11). For SDK 12 see this link ). If you don't want to use fds, you can look into using the write/erase flash softdevice functions(e.g. sd_flash_write), but I would suggest giving fds a try first.

Hi pallavi,

I see that you have not uploaded your code(main.c, etc) on MyPage, only the keil-project file, but that file does not include any code itself. So you should zip the ble_app_uart folder, and upload it on MyPage.

hello daniel sir, my main code is too long its around 4000 lines code.so that i think its difficult to post.but i have attached my code file in test case on my page.is it possible to see my code there.if its impossible then tell me accordingly so that i can post my code here. Thank you, Pallavi

You could also do a debug session, and see if you are running into the error-handler. See this post on how to debug.

why do you think it's a RAM issue? Could you post how your main.c code looks like ?
