This information is outdated. There’s no need to do these modifications with the new development kit and the new toolchain (version 2023 and up).
Summary
There is a step which you need to do to make Bluetooth the Onethinx Core Development Kit work.
Go to: cy_ble_clk.c (BLE middleware)
Comment out the entire:
if((Cy_SysLib_GetDeviceRevision() != CY_SYSLIB_DEVICE_REV_0A) && (SFLASH-
>RADIO_LDO_TRIMS != 0U))
{
...
}
In the future version this will not be necessary.
Furthermore, to make it work, you must solder a 3cm wire to the BLE_antenna pin on the Development Kit as seen in the picture bellow.
