The nRF51422 CEAA chip is a very old one. It's the first chip version and should not be used with S110 v8.0.0 as mentioned in the release note. I would suggest you to get hold of a new version 3 chip. It's available in the nRF51 DK development kit.

Hi Hung Bui,

I am using Rev 2 Hardware. SDK 7.2.0 and softdevice S110 7.1.0 how much maximum blocking period in this hardware revision.

Rev2 Hardware has 6 bytes buffer, but it doesn't support the new S110 that don't have CPU non-blocking option, so the maximum CPU blocking period is 6ms. Please see section 11.3.2 in the S110 Softdevice Spec v1.3 (the spec v2.0 is for S110 v8.0)
