Same thing on iOS 12.1.4 on my iPhone XS (that's why I tried the beta 12.2 to see if it would fix it). iPhone 6S works great. Tried an iPhone X and it is showing the same issue. nRF Connect on a PC works perfect. I believe it is an Apple iOS issue. I will try on an iPhone 7 later today which has not been upgraded to 12.1.4 and then I will upgrade it to see if that is what is causing the issue.

Hi,

Could you test with nRF Connect and see if you see the same issue?

Also iOS 12.2 is a beta version so I think it might be the reason for not working.

I'm having the same problem. Updated my iPhone XS to iOS 12.2 and now it will only show the BLE devices but not connect to them. Using SDK nRF5_SDK_14.2.0_17b948a and s132_nrf52_5.1.0_softdevice.hex

It has been absolutely solid until the upgrade. The exact same app works on an iPhone 6S but not the iPhone XS. Same exact firmware works with iPhone 6S but not iPhone XS. LightBlue shows the devices but will timeout when connecting. My custom app discovers the service but the characteristics are not being found. Everything works great on the iPhone 6S that has not been upgraded to the latest iOS version and LightBlue also works great on it.

I will try to get a hold of an iPhone 6 and test this, could you give me a step-by-step procedure on what you are doing to test this?

In the mean time, can you try testing with a newer iPhone model and see if it makes any difference?

Hi Mttrinh:

iPhone connect with nrfConnect but disconnect after 30 seconds.

I've revised it. But I don't know why.

Add

static void ble_evt_handler(ble_evt_t const * p_ble_evt, void * p_context){

.........

case BLE_GATTS_EVT_SYS_ATTR_MISSING:
// No system attributes have been stored.
err_code = sd_ble_gatts_sys_attr_set(m_conn_handle, NULL, 0, 0);
APP_ERROR_CHECK(err_code);
break;

.........

}

Hi,

I tried your code and manage to connect with both my Android phone(Nexus 6 Android 7.1.1) and my iPhone X(iOS 12.1.4) using nRF Connect. Couldn't connect with the LightBlue app though. Could you try with another iPhone using nRF Connect and see if you can connect?

I will have a look at the code and see if I can reproduce the issue. I will update you as soon as possible.

What example from the SDK are you basing your application on?

Also, have you tested with other iPhones(7, 8 or X)?

Hi,

Could you provide me with more information, which SDK are you using? Which Softdevice?

What example are you using? Is it modified or unmodified?
