The help that you did to me, i have no words at all. I see Nordic developer zone as one of the best discussion forums across.

Thanks Jorgen again. Have a nice day.

Hello Jorgen,

I am very much happy with your help. Although i am using a free version of Keil5 due to which the code limit is 32k and the one you sent to me is exceeding it.

I probably cannot fund to get a licensed version. Can u help me with the same problem in sdk14.1.0? with me using Segger Embedded Studio?

Or maybe if it can be done on sdk 12.2.0 where code size remains lesser than 32k? I have been doing it on sdk12.2.0. I am attaching my zip file.

ble_app_uart

I appreciate your help.

Thank You.

I uploaded an example in my above answer. Note that only PCA10040 board and Keil5/GCC projects are updated with correct files. Let me know if you are using other compiler, or want projects for PCA10056 board.

If you could share some code snippet for it then it would be very helpful. If you could. Thanks in advance.

Hi,

When using the ble_app_uart example, the data received over BLE can be handled in nus_data_handler. Here you should be able to write to the sd card in the same way done in the fatfs example, by replacing the parameter TEST_STRING and sizeof(TEST_STRING) in call to f_write with the received data from p_evt->params.rx_data.p_data and length from p_evt->params.rx_data.length.

[EDIT]: Attached an example that combines ble_app_uart and the fatfs example, to write all strings received over NUS/BLE to SD Card. The example is written for SDK 14.0.0. Extract the zip in \examples\ble_peripheral\ directory.

ble_app_uart_fatfs.zip

ble_app_uart_fatfs_sdk141_keil_gcc_ses.zip

Best regards,

Jørgen
