About esb_ptx_ble & esb_prx_ble.

[Leo Mo]

Can I copy the ESB code from SDK v3.3.0-preview3 into SDK v2.9.0, and then get the functionality in esb_ptx_ble & esb_prx_ble?

 

Is there any way to achieve it quickly?

Hello,

Not sure I understand what problem you are trying to solve here, there should be ESB example projects for the nRF52840 in both the nRF Connect SDK releases you are referring to.

Can I copy the ESB code from SDK v3.3.0-preview3 into SDK v2.9.0, and then get the functionality in esb_ptx_ble & esb_prx_ble?

There may be some api changes, but for most part I would expect it should be pretty straight forward possible yes.

Hello,

Using nRF Connect SDK v3.3.0, one device runs esb_ptx_ble and broadcasts 2 packets of data every 5-10ms, with 15 devices running esb_prx_ble，esb rx interval 7300ms，rx window 15ms， 30 seconds is a receiving cycle, and failure to receive a packet of data within the cycle is considered a failure; After running 15 devices for a few days, occasionally one device experiences dozens of consecutive cycles without receiving data. Why is that?

CONFIG_CONN_INTERVAL_MIN=990  //ms

CONFIG_CONN_INTERVAL_MAX=1010

CONFIG_CONN_LATENCY=6

Is it phase entanglement? Or is it another question? How can I solve it?

[Kenneth]

Do you set config.selective_auto_ack = true; before calling esb_init(&config);?

Do you set tx_payload.noack = true; before calling esb_write_payload(&tx_payload);?

Yes, Both variables are set to TRUE.

Hello,

For the device that occasionally experience dozens of consecutive cycles without receiving data, is the device in a BLE connection or is it advertising at the time? What is the connection or advertisement interval at the time?
