BLE connection takes long time with SDK17.1.0 example

Hi,

I am currently evaluating BLE long range feature for one of the our product. for this, using two nRF52840 dongle PCA10059. One used for peripheral and another for central. Using SDK 17.1.0 examples and S140.

When central initiate connection with Peripheral, it takes random too much time for successful connection from 3mins to 10mins sometime after SUCCESS response from API sd_ble_gap_connect. Even if I disable PHY_CODED, facing same issue. what could be the reason?

Let me know if more info required for any configuration.

Regards,

Bipin Patel
