How to build gazell communication using nrf52810 + rfx24l01C？

[zp]

The SDK version I am using is V15.0.0.

I use the function interface nrf_gzll_set_pa_lna_cfg 。The following is my configuration information：

static nrf_gzll_pa_lna_cfg_t m_pa_lna_cfg = {
.lna_enabled = 1,
.pa_enabled = 1,
.lna_active_high = 1,
.pa_active_high = 1,
.lna_gpio_pin = 22,
.pa_gpio_pin = 23,
.pa_gpiote_channel = 0,
.lna_gpiote_channel = 1,
.timer = NRF_TIMER2,
.ppi_channels[0] = 12,
.ppi_channels[1] = 13,
.ppi_channels[2] = 14,
.ppi_channels[3] = 15,
.ramp_up_time = 1,
};

Found the following problems after running：

1、The signal got a magnification of about 10db。

2、High data packet loss rate。

3、Gzll communication can be received, easy to send failed。

Hi,

Have you taken a look at out Gazell Device/Host example? https://www.nordicsemi.com/DocLib/Content/SDK_Doc/nRF5_SDK/v15-0-0/gzll_examples_device_and_host

To use PA/LNA control, set the GZLL_PA_LNA_CONTROL flag to 1 in sdk_config. Note that this example has been tested with the SKY66112 front end; control pin connections might be different for other PA/LNA modules.

Best Regards,

Marjeris

Thank you for your reply，I am modified according to the example

nRF5_SDK_15.0.0_a53641a\examples\proprietary_rf\gzll\gzll_ack_payload\device

1、Will gzll static library only adapt to SKY6612

2、If using rfx24l01c, is there an example?

1. There is no specific requirement to use the SKY6612. The PA/LNA pins are "generic" and can be connected to any PA/LNA module:

2. Not that I am aware of.
