Question

Hi all, 
 My device is working as a HID device. it's working on android and iPad but not work on macOS. It's can't solve the security procedure and returning error: <info> peer_manager_handler: Connection security failed: role: Peripheral, conn_handle: 0x0, procedure: Bonding, error: 1 
 I was trying to connect to macOS 10.13.6 High Sierra using ble_app_hids_keyboard example. But I got the same error. 
 My device using NRF52810 with s112 and SDK 15.3.0. Ble_app_hids_keyboard project I had run on pca10040 board with s112 and SDK 15.3.0. The only thing which I changed in ble_app_hids_keyboard example is sdk_config.h 
 #define NRF_LOG_BACKEND_RTT_ENABLED 1 
 
 #define NRF_LOG_DEFAULT_LEVEL 4 Can you help me? Many thanks in advance.

Everything strangely works on our devices. History: The customer has a connection problem. The problem is that there was no connection on the imac device, i.e. nothing happened when connecting. I assumed that this is because I used a test randomly generated mac address in the firmware. Therefore, I generated a new mac address based on hardware. The code: 
 err_code = sd_ble_gap_addr_get (& hardware_mac);
APP_ERROR_CHECK (err_code);
hardware_mac.addr [5] & = ~ (1 << 4);
err_code = sd_ble_gap_addr_set (& hardware_mac); 
 And I was able to connect on my iMac. I did the same trick with DK 10040. And a miracle happened. An example from nordic connected to iMac. Those. I changed the standard example from nordic so that it would work. Compiled code did not connect to imac by default.

Hi! I checked on the new MacBook pro and it worked, It seems that something is really wrong with our devices. Two mac mini one iMac and MacBook don't seem to work with BLE. Of course, BLE support is declared in the device parameters, but I still do not believe that they are all broken. There is a possibility that due to the noisiness of the radio or some software problems. In any case, if I find out the reason, I will write here.
