Hi All

CC2640 STACK:V2.2.2

My project needs BLE 4.2.

Consider the project of code size, I can enable "-DBLE_V42_FEATURES=PRIVACY_1_2_CFG" on build_config.opt.

But I found that the time service doesn't work as long as this parameter is enabled.

What should I do to make the time service work?

Thanks a lot.

Hi,

What do you mean with "does not work"? Could you please elaborate in more detail.

Thanks for your reply.

Normally, the example code "TimeApp" will update the time from phone to device(cc2640) after connected & paired.

But as long as I enable this flag "-DBLE_V42_FEATURES=PRIVACY_1_2_CFG" in build_config.opt,

he can't update the time.

My project needs BLE4.2.

And enable this parameter will not cause my code size to exceed.

Have you analyzed the OTA traffic with a sniffer to figure out what is different?
