    Write long value fails



      I'm not able to perform a write operation on a long attribute. I've added a custom service with a characteristic of attribute length 50.


      I've set the GATT MTU size as 23 on windows CySmart application and also on the On-chip side(Top design/GAP settings tab).


      Now when I try to write 50 bytes value (which I've read previously using the "Read Long Value"option), I immediately get an error:"Write long characteristic value failed. Request is not supported by the peripheral device".


      Can you please tell me what's the problem.


      Thanks & Regards,
