ble disconnects Immediately after connection.

[viswa]

Hi All,

I'm using nrf Connect SDK v1.7.0 with Vs Code

So here I can see in the debug prints that Bluetooth device is able to get connection successfull callback and Immediately I get disconnection callback with this error reason.

BT_HCI_ERR_CONN_FAIL_TO_ESTAB           0x3e

I wish to know, what does it mean and how to prevent it?

Hmm, okay. What environment are you testing your application in? Are the devices located right next to each other? You can try increasing the TX power (example here) on your peripheral devices.

Can you share some more details on what samples exactly the central/peripherals are based on?

A sniffer trace of the connection might give us a better idea of what the problem (on air) is.

Best regards,

Simon
