Hello, Einar.

Thank you for the suggestion; it worked.

Hi,

I see the same on my end now. You cannot do it in the connected callback, but need to wait until that has returned. When I do it from the main loop, I get correct readings using the same code as you use, plus this way to get the default conn handle that I added in the connected callback (default_conn_handle is a uint16_t that is declared on the outside):

	int rc = bt_hci_get_conn_handle(conn, &default_conn_handle);
	if(rc)
	{
		printk("fail getting conn handle");
	}

Hi Einar,

Thanks for the advise. In fact, I had tried that one as well by getting conn_handle in the connection callback, but the issue remains the same.

Hi,

In this snippet I do not see that you set default_conn_handle to a sensible value anywhere. Did you not just include that code, or is this uninitialized? You can use bt_hci_get_conn_handle() to get the handle.
