We designed a board using BlueNRG-2 and we uploaded the GPIO demo code available in BlueNRG-2 navigator (to toggle DIO14) to the board using the BlueNRG-ST- Link utility. The board didn't detected with high Frequency(.9MHz-4Mhz) so we changed the SWD frequency into 480Khz. Then board connected and programmed successfully. But code didn't work. could you please check on this issue and please update what we can do in order to work our board.Please find the attached Schematics and the demo code for reference. Please consider and respond as soon as possible
