NRF-52832 Device disconnects after 30 seconds on IOS

Hello, I assembled my own PCB with nrf52 and program it yesterday. Problem with disconnected not occured like on NRF52DK. The only significant difference with this two PCB is XTAL. I don't have 32.768 kHz external crystal, ony 32MHz. So I thing the reason of disconnected were wrong timing.
SoftDevice clock:
Source: RC
CTIV: 0x10
Accuracy: 250PPM
Best regards and thank You Kenneth for Your involvement

Then it may seem as we need an nRF sniffer log yes, likely it is something obvious, but I can't think of anything at the moment. In general you may check out this link:

I pasted this case in pm_evt_handler() but still not working. I set breakpoint inside and case is not done. 🙂

I checked all of the cases on switch (switch (p_evt->evt_id)). No one never has passed.

edit: Unfortunately , I haven't received my PCB board yet, will try to get log in Monday. Best Regards

Hi,

Can you try to allow re-pairing by adding the following in pm_evt_handler() in main.c:

case PM_EVT_CONN_SEC_CONFIG_REQ:
{
// Allow or reject pairing request from an already bonded peer.
pm_conn_sec_config_t conn_sec_config = {.allow_repairing = true};
pm_conn_sec_config_reply(p_evt->conn_handle, &conn_sec_config);
} break;

Best regards,
Kenneth

Hello, thank you for interest. Unfortunately now I check my test code on DK (PCA10040) and can't use it like nRF Sniffer. On end of the week, I should pick up my PCB board and assembly it. Then I can use DK like nRF Sniffer.

I use SDK : nRF5_SDK_15.2.0_9412b96
, oryginal example

"\nRF5_SDK_15.2.0_9412b96\examples\ble_peripheral\ble_app_gatts_c"

also not working, It means disconnected iPhone after ~30 seconds. ( It contains gatt_init())

Best Regards
Mateusz

Do you have a sniffer log? For instance using nRF Sniffer?

What SDK example have you used in which SDK release?

Make sure you have included gatt_init() in your project, since that will handle the MTU procedures.

Best regards,
Kenneth
