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

Hi Eric

Which microcontroller are you using?

If I add code after 473 lines

rx_payload.noack = true

Have you tried this yourself?
If so, did it disable the ack in the rx payload as expected?

Hi Nordic Engineer,

Thank you for your reply

I use nRF52811

I tried, but the synchronization problem I encountered couldn't be solved

Can I describe my application scenario?

I hope there are more devices(nRF52811)

But let me assume 3 devices first

The burning procedures of these 3 devices are the same

It means that any device can be paired with a mobile phone (User autonomy)

But the phone will only pair with 1 device (I call it relay)

The remaining 2 unpaired devices will be in ESB_ RX status

These 2 devices should receive the data sent by "relay" in time

After the mobile phone sends data, "relay" and device should be synchronized as much as possible

To do this, I want to turn off all "ack"

In addition, I tried to turn off another "ack"

nrf_esb_config.selective_auto_ack = true;

This did not make the effect better

So what should I do?

Thank you

Hi ,

Can you answer this question, please?

Thank you

Hi Eric

Try to use

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

on the "relay" and only

nrf_esb_config.selective_auto_ack = true;

on the two other devices.

Does this fix your issue?

Hi,

I tried to turn off ack

But there are still out of synchronization

Any of my products can be used as "relay"

So their program are the same

Under this premise, all products (including "relay")

Both lines of code will be executed

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

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

I'm thinking about a problem

"relay" after pairing with mobile phone

"relay" sends an instruction to notify the nearby device to turn off Bluetooth

Do you think this way can solve the synchronization problem?

Thank you
