Timeslot ESB PRX becomes stuck soon after PTX keeps sending message.

[XiongYin]

Hi,

PTX: based on the SDK11 "\examples\proprietary_rf\esb_ptx\pca10040\blank\arm4\esb_ptx_blank_pca10040.uvproj", what I changed is delete the "nrf_delay_us(50000)" in main(), to make it sends ESB message more quickly.

PRX: based on the code devzone.nordicsemi.com/.../0b06eda14f86904e772113776c11034e, what I changed is "nrf_esb_config.mode = NRF_ESB_MODE_PRX". It will hit the app_error_fault_handler after few seconds.

Both PTX and PRX run at PCA10040(V1.1.0 2016.11), you can find the code in this attachment below, thank you very much!

Hi XiongYin,

Thanks for the detailed information and the demo code.

We found that it was due to a bug in the implementation of nrf_esb.c

So if you in nrf_esb_stop_rx() modify :

if (m_nrf_esb_mainstate == NRF_ESB_STATE_PRX)

to

 if ((m_nrf_esb_mainstate == NRF_ESB_STATE_PRX)||(m_nrf_esb_mainstate ==NRF_ESB_STATE_PRX_SEND_ACK))

It should work. Please let me know if the issue still occurs.

Hi Hung Bui,

It works now, the issue doesn't occur in about half an hour. I'll keep testing to see if it works too when running for long time.

Thank you!
