Is beacon rev.1.1.0 compatible with softdevice s110 V8.0?

[John]

Hi, I have nrf51822 bluetooth smart kit Rev 1.1.0 . Is this beacon compatible with Softdevice110 V8.0? I want to know this because I have read that "The CPU will by default be available for the application during RF activity" at this version of softdevice. Thanks in advance!

It depends on what chip revision of the nRF51 you have. You need to compare the device markings of your chip with Table 2 in the nRF51 Series Compatibility Matrix to figure out what revision you have. Then you check Table 4 to see what SoftDevices and SDKs that are compatible with your chip.

If you use SoftDevice S110 8.0.0 with a revision 2 chip you should enable mutual exclusion between the radio and the application. Please see the Changes section in the S110 8.0.0 release notes for more information.

uint32_t opt_id = BLE_COMMON_OPT_RADIO_CPU_MUTEX;
ble_opt_t cpu_blocking_enabled;
cpu_blocking_enabled.common_opt.radio_cpu_mutex.enable = 1;
ble_stack_init();
err_code = sd_ble_opt_set(opt_id, &cpu_blocking_enabled);

I can't check what revision is on the 1.1.0 now, but I can on Monday, please add a comment if you can't figure it out.
