Hi y'all.
I've been developing in Zephyr NRF52840. My code is based in Central_HR_Coded (SDK 2.6.1, Toolchain 2.7.0). I had some issues with the bt_conn_disconnect function. This function is being called after a command in the uart stack that triggers this function in this way:
ISR UART -> Work Queue (with k_work_summit) -> callback of disconnection request:
static void disconnection_request(void)
{
if (curr_connection) {
int err = bt_conn_disconnect(curr_connection, BT_HCI_ERR_REMOTE_USER_TERM_CONN);
if (err) {
LOG_ERR("Disconnection failed (err %d)", err);
send_err_data(FRONTEND_ERR_DISCONNECTION, err);
} else {
LOG_INF("Disconnection requested");
}
} else {
LOG_INF("No active connection to disconnect");
}
}
curr_connection variable is define using bt_conn_le_create. The issue is I'm getting Error -128 in the bt_conn_disconnect function, which means literally ENOTCONN /* Socket is not connected */.
This is happening because curr_connection.state property is retrieving BT_CONN_DISCONNECTED, but i can assure that both devices are connected due to notifications in a service. I already discard the fact I'm possibly using this function in a interrupt routine. (105524/bt_conn_disconnect-got-errors).
I want to know why this error is popping and also how can i workaround it. What gives?
