Is there an mbed library or example for nRF52x devices?

There are nRF52832-based boards listed as mbed compatible, but I have not been able to locate any example programs or libraries specifically for the nRF52 family of devices. I see the shield library for the BlueNRG when I pull some of the BLE examples, even when the target is nRF52, but don't see any evidence of direct nRF52 BLE support.

The mbed BLE API requires that a controller driver be written below the API layer. Does that exist for the nRF52 family?

Hi,

please look at https://github.com/ARMmbed/mbed-os-example-ble - NRF52-DK should work

The page does say that the nRF52-DK has been tested against the example programs, but I am not able to locate any nRF52 BLE Controller libraries referenced from that repo, though under "shields" you can follow a link to the BlueNRG shield library.

If you have a link, please, please share it. Thank you.

For reference, when I go to github.com/ARMmed and search for a repo using "nRF" I get a list of nRF51x libraries, but no nRF52x libraries:

See https://github.com/ARMmbed/mbed-os/tree/master/targets/TARGET_NORDIC/TARGET_NRF5x/TARGET_SDK_14_2 - this is the SDK that is being used. There's softdevice hex file. I believe this is the one you are looking for.

I attempted to compile the BLE_URIBeacon in the online compiler for the nRF52-DK and it failed. However, I was able to compile and run the BLE_BatteryLevel example in the online compiler, so at least one example program does run.
