Transferring data received over ble to sd card

[YASH]

Hi All,

I am working on pca10040, nrf52832 and s132. I am using ble_app_uart and sd card, where i want to transmit data received over ble to the sd card.

Can you help me with how can i do so?

I have the project ready where both sd card and ble functionalities are there. I am able to advertise and recieve data over ble as well as execute sample .txt data transmission over to sd card as demonstrated in fatfs example.

I want to know on how i can transmit the text received over ble to the sd card in a .txt file.

Thanks in advance, Regards

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.

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

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.
