flash data storage on nRF51822 using mbed online compiler?

[Hari Charan]

Anyone had a successful attempt at using the fds(flash data storage) module(http://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.sdk5.v11.0.0%2Flib_fds.html&cp=4_0_0_3_30) on the nRF51822 on the mbed online compiler? I've been trying to make it work like in http://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.sdk5.v11.0.0%2Flib_fds_usage.html with many errors(fds_evt_t not defined etc.) Where can I find a working example code for mbed-nRF51822-fds? Thank you in advance.

FDS is used by Peer Manager, which is implemented in mbed for nRF5x devices. Which mbed OS version are you using, and how are you using the library? Could you share your project?

I'm using mbed OS 2 with the online compiler. drive.google.com/open Here are the project files.I'm using older versions of the BLE_API and the nRF SDK for compatibility with another main project. Ignore the original.cpp in the project files. The first error is "Error: Incomplete type is not allowed in "main.cpp", Line: 50, Col: 7" where the event handler is being declared. The cause for the error seems to be "fds_evt_t not found". Please point out if I missed any includes or if I did anything else wrong. Thank you!

Hi,

The FDS library included in your mbed project is from SDK v10.0.0, while the code you have put in your main.cpp file is for FDS in SDK v11.0.0 or newer. fds_evt_t is not declared in the old version, and this is the reason why you are getting these errors. If you need to keep the old libraries, you need to refer this documentation for details on usage of the FDS library.

Best regards,
