Host reception by gazell is not successful

[desi_ronizer]

Hello, I have a question.

The chip uses nRF 52832. MDK keil μVision V 5.22.0.0 is used as the development environment. I am using nRF5_SDK_13.0.0-1.alpha_055eef3. It is based on template_project. I uploaded the source to onedrive.

host 1drv.ms/.../s!Avi3XPNJyYutgn6Gch-9r7WOZtqC

device 1drv.ms/.../s!Avi3XPNJyYutgn0weoveuPfRzt7V

When the button of the device is pressed, nrf_gzll_add_packet_to_tx_fifo is called, and host illuminates the LED with nrf_gzll_host_rx_data_ready.

Communication was successful several times, host confirmed that nrf_gzll_host_rx_data_ready, device nrf_gzll_device_tx_success is called in the callback.

However, when communicating several times, host will not receive it. At that time, device calls nrf_gzll_device_tx_failed, but I do not know the reason for not returning.

How should I do it? Thank you for your consideration.

The tx FIFO and rx FIFo on the device side are filled and transmission seems to have failed.

The packet is counted and managed, and the transmission becomes stable. However, as a result, the timeslot number is 2 and the smallest timeslot is 600 us so it was found that the requested specifications can not be satisfied because the fastest communication is 1 to 1.2 ms.

Therefore, I will try it with ESB. thank you for your answer.
