FDS on nRF52832 using mbed with SDK14.2

[Peter Kmet]

I'm stuck over fds_init() which hangs on mbed-os using SDK 14.2

I am calling fds_init within bleInitComplete callback as follows:

BLE &ble = BLE::Instance();

ble.onEventsToProcess(scheduleBleEventsProcessing);

ble.init(bleInitComplete);

Unfortunately MCU hangs few ms right after fds_init completes. Advertising not started yet at that moment.

Any idea ?

Thanks.

Hi Peter.

Can you ask this question directly to mbed here?

Best regards,

Hi Peter.

Can you ask this on mbed's forum?

We don't have any official support for mbed at the moment.

Best regards,

Andreas

Yeah, https://os.mbed.com/questions/85602/fds-on-mbed/  . Some similar questions are unanswered more than year. Brings me question if mbed platform is suitable for commercial projects at all (although small scale) with missing support. Unfortunately, there is no viable alternative if you want to use something more high level besides Nordic SDK (which is C-based).

Anyway, could be something deep inside mbed ble implementation, mbed has some FlashIAP which looks like uses fstorage on background however issue (hang) looks similar. Will try investigate further, now I am leaning toward using external serial flash although it is waste of resource not to use quite huge on-chip flash (512kB).

Hi.

mbed is a SW package delivered by Arm and is supported through the mbed website. Nordic delivers the nRF5 SDKs to support development on our nRF5 series parts and this will be the recommended solution to use, this is fully supported by Nordic. Since we have open sourced our SDKs you will find that parts of the mbed adaptation for nRF52 devices is coming from our nRF5 SDK. These parts are fully tested by us as part of the nRF5 SDK release process, but we can can't guarantee that the integration with mbed doesn't break the functionality. Please do keep in mind that mbed is just one out of a large amount of third-party SW packages out there supporting the nRF52 devices where most of them are using parts from our SDK.

Best regards,

Andreas
