Hi,

The built in API CyBle_AesCcmEncrypt shows a 27 byte size limit for the data encryption.  Is there a reason that 27 is the limit?  Any way to bypass?

Thanks, Dave

Hello,

Based on the algorithm implementation, the hardware registers of BLE Link layer encrypt data registers are limited for maximum of 27 Bytes only. So the length of the data to be encrypted is limited to 27bytes.

Thanks,

P Yugandhar.
