Hi all,

   

I have Cy8CKIT-042-BLE.

   

I have been following video 3 on http://www.cypress.com/training/how-make-ios-app-control-robot-using-bluetooth-low-energy-ble

   

When I configure my BLE GAP settings Peripheral role, advertisement packet, it give me the error, error 1: the advertisement packet length exceeds the max length of 31 bytes.

       

thanks,

Hi,

   

Advertisement packet size is 31 bytes max. Out of which only 22 bytes are in your hand, which includes service UUID and device name.

   

if 2 byte / 16-bit service UUID then max size of device name is 20 bytes

   

if 4 bytes / 32-bit service UUID then max size of device name is 18 bytes

   

if 16 bytes / 128-bit of service UUID then max size of device name is 6 bytes.

   

If you want to use 128-bit characteristics and also want to advertise with a longer name, use a 16-bit service only for advertisement purpose. By doing so you can use 128-bit Services, characteristics etc and can also advertise with al onger name i.e. 20 Characters.
