Hi, my GATT design includes 7 services (maximum 4 characteristics for each service). I am using nrf connect desktop application to implement this design but getting an error NRF_ERROR_NO_MEM. What could be the possible solutions?

Hi,

Try to increase NRF_SDH_BLE_GATTS_ATTR_TAB_SIZE and/or NRF_SDH_BLE_VS_UUID_COUNT in sdk_config.h

Can you mention how can I access the sdk_config.h in nrf connect desktop application.

 That's not possible. You would need to re-compile the connectivity fw (and apply pc-ble-driver patch + adjust ATTR_TAB_SIZE).

Try this hex-file: connectivity.zip

If you get this pop-up,
...

then click "No".
