I'm trying to run the HID composite example on a nRF52840 dongle, and its not working:
- I refer to : nRF5_SDK_17.0.2_d674dde\examples\peripheral\usbd_hid_composite\pca10056\blank\ses\usbd_hid_composite_pca10056.emProject
- set CONFIG_HAS_MOUSE = 0
- set NRF_CLI_ENABLED = 0
- I changed the preprocessor from PCA_10056 to PCA_10059
- I changed the settings in Linker for FLASH and RAM, as described in the tutorial
- code compiles without any problems
- the dongle is programming mode (red LED)
- I'm using nRF connect for desktop v3.7.0
- I'm able to write the HEX file to the dongle - red LED goes off
But now I would expect that my PC detects a new USB keyboard, but nothing happens - I press SW1 : nothing happens
Any idea what is wrong
Also, with nRF Connect I'm not able to "erase" or "erase & write" - these items are grayed out - any idea, why ?
These are two brand new dongles and I have no idea whats wrong.
I followed the same instructions to compile the blinky example for the dongle - this works well, all LEDs are working well
best regards, Matthias
