Direction finding connectionless rx "Waiting for periodic sync... failed (err -11)"

Question

Hello,

I am working on direction finding connectionless locator/beacon (AoA).

I ran into a problem in the locator. Everything works fine until "Waiting for periodic sync... failed (err -11)"

RX console log:

I use sample code NRF/direction_finding_connectionless from nRF connect SDK v2.1.1.
For locator I use custom antenna array 3x3 (8 segments) with ubx Nora B101 (nRF5340).
Beacon is also custom with ubx Nora B101 (nRF5340).
Build board is based on nrf5340dk_nrf5340_cpuapp.

According to the readme file, I modified the files (locator)
boards/nrf5340dk_nrf5340_cpunet.overlay

&gpio_fwd {
    dfe-gpio-if {
        gpios = <&gpio0 29 0>,
            <&gpio0 28 0>,
            <&gpio0 30 0>,
            <&gpio0 31 0>;
        };
};

&radio {
    status = "okay";
    /* This is a number of antennas that are available on antenna matrix
     * designed by Nordic. For more information see README.rst.
     */
    dfe-antenna-num = <8>;
    /* This is a setting that enables antenna 12 (in antenna matrix designed
     * by Nordic) for Rx PDU. For more information see README.rst.
     */
    dfe-pdu-antenna = <0x0>;

    /* These are GPIO pin numbers that are provided to
     * Radio peripheral. The pins will be acquired by Radio to
     * drive antenna switching when AoA is enabled.
     * Pin numbers are selected to drive switches on antenna matrix
     * desinged by Nordic. For more information see README.rst.
     *
     * NOTE: Make sure to select the same GPIOs in the application core DTS
     * overlay's gpio_fwd node.
     */
    dfegpio0-gpios = <&gpio0 29 0>;
    dfegpio1-gpios = <&gpio0 28 0>;
    dfegpio2-gpios = <&gpio0 30 0>;
    dfegpio3-gpios = <&gpio0 31 0>;
};

main

static const uint8_t ant_patterns[] = { 0x0, 0x4, 0x2, 0x6, 0x1, 0x5, 0x3, 0x7};

in beacon file I add AoD config into project config.

Are there any other changes required, or what could cause this error?

Thank you.
