When I need to switch between 1M and 2M
I create an object of the type bt_conn_le_phy_param and fill in the parameters appropriate to the radio mode I want, and then I call the method bt_conn_le_phy_update(), and it works well.
For example:
const struct bt_conn_le_phy_param preferred_phy = {
.options = BT_CONN_LE_PHY_OPT_NONE,
.pref_rx_phy = BT_GAP_LE_PHY_1M,
.pref_tx_phy = BT_GAP_LE_PHY_1M,
};
err = bt_conn_le_phy_update(conn, &preferred_phy);
if (err) {
LOG_ERR("bt_conn_le_phy_update() returned %d", err);
}
or
const struct bt_conn_le_phy_param preferred_phy = {
.options = BT_CONN_LE_PHY_OPT_NONE,
.pref_rx_phy = BT_GAP_LE_PHY_2M,
.pref_tx_phy = BT_GAP_LE_PHY_2M,
};
err = bt_conn_le_phy_update(conn, &preferred_phy);
if (err) {
LOG_ERR("bt_conn_le_phy_update() returned %d", err);
}
but when I try to use this same approach for CODE PHY
const struct bt_conn_le_phy_param preferred_phy = {
.options = BT_CONN_LE_PHY_OPT_CODED_S8,
.pref_rx_phy = BT_GAP_LE_PHY_CODED,
.pref_tx_phy = BT_GAP_LE_PHY_CODED,
};
err = bt_conn_le_phy_update(conn, &preferred_phy);
if (err) {
LOG_ERR("bt_conn_le_phy_update() returned %d", err);
}
the method return
bt_conn_le_phy_update() returned -5
I enabled the logs for the bt_hci_core and bt_conn files and the logs returned are these

In the prj.conf file I added the configuration
CONFIG_BT_USER_PHY_UPDATE=y
and in main file I put
#define BT_CONN_LE_PHY_PARAM_ALL
in an attempt to help resolve it, but I was unsuccessful
I'm out of ideas,
Could someone help me make it work? Thanks
