How does BLE + ESB receive?

[eric_cheng]

Hello Nordic Engineer,

I'm a beginner

In this GitHub

If I add code after 473 lines

rx_payload.noack = true

what will the final result be?

Thanks

I don't quite understand the specific effect...

But I turned them all off

nrf_esb_config.selective_auto_ack = true;
rx_payload.noack = true;

=========================

I describe my current approach

Can you correct me if I'm doing something wrong?

I used Timer1 to switch TX and RX In 《timer_event_handler》

state = !state;

if(state == true) 
	{		
		//memcpy(&nrf_esb_config, &tmp_config, sizeof(nrf_esb_config_t));
		nrf_esb_config.payload_length     = 2; 
		nrf_esb_config.protocol           = NRF_ESB_PROTOCOL_ESB_DPL;
		nrf_esb_config.retransmit_delay   = 1000;
		nrf_esb_config.bitrate            = NRF_ESB_BITRATE_2MBPS;
		nrf_esb_config.event_handler      = nrf_esb_event_handler;
		nrf_esb_config.mode               = NRF_ESB_MODE_PTX;
		nrf_esb_config.tx_output_power		= NRF_ESB_TX_POWER_4DBM;
		nrf_esb_config.selective_auto_ack = true;
		nrf_esb_config.radio_irq_priority = 0; 
	}
	else
	{
		//memcpy(&nrf_esb_config, &tmp_config, sizeof(nrf_esb_config_t)); 
		nrf_esb_config.payload_length     = 8;
		nrf_esb_config.protocol           = NRF_ESB_PROTOCOL_ESB_DPL;
		nrf_esb_config.bitrate            = NRF_ESB_BITRATE_2MBPS;
		nrf_esb_config.mode               = NRF_ESB_MODE_PRX;
		nrf_esb_config.event_handler      = nrf_esb_event_handler;
		nrf_esb_config.selective_auto_ack = true;
		nrf_esb_config.radio_irq_priority = 0;
	}

I don't know if it is correct to use timer to change TX and RX?

Thank you

Hi,

I suggest to get an PPK II, then you can see in real-time based on the current consumption when it's in rx, tx, idle, and switching. This will make it much easier to see how your changes affect timing etc.

Best regards,
