We have 3 devices , 1 central-peripheral and the other 2 peripheral devices (client), all nrf52840 custom board. The central-peripheral device should scan and connect the 2 peripheral device. When the central device is in close proximity (~10 cm) of the both the peripheral devices , the connection is smooth and stable, but if we place the peripheral devices at a distance of ~1m, the devices gets disconnected as soon as it gets connected with disconnection error 0x3e very frequently. What may be the reason? Is there anyway to avoid this? I am using SDK 15.3 soft device s140.
