Hi Joe, No, we need an address match, otherwise we will pickup lots of noise.

A followup question, if I know the channel, is it possible to set up the nRF52DK to listen and report from all addresses from nRF2401 which used ShockBurst. Essentially, I try to find out the address used by the nRF2401 transmission.

Yes, it should work. There is a small bug with DynamicACK in SDK v12 and 11, if you don't use dynamic ACK then it should be fine.

Hi, I am using nRF52832 and SDK 12.2. I need to be able to receive the shockburst packets from a nRF2401. Will this micro_esb work?

Libra, I just tested here and it worked for me. I attached the modified example in the Answer. Note that I used the micro_esb example here. Not the mico_esb_uart one. If you test using NRF51DK, you should be able to see on the PRX LED1 blinking every time it receive a packet.

@Hung Bui： testing between 2 nRF51 devices

@libra: Do you mean that you are testing between 2 nRF51 devices ? not with the nRF2401A, nRF2402,NRF24E1 and RF24E2?

hi hung bui，I reference to "Getting started with micro-ESB on nRF51"link text when Set the protocol to uesb_config=UESB_PROTOCOL_ESB_DPL,it is ok. But set the protocol to uesb_config.protocol = UESB_PROTOCOL_SB instead of UESB_PROTOCOL_ESB_DPL.

Please let me know more about your set-up. Which chip did you use to test ? How you tested it ? Did you mean that it would work with "UESB_PROTOCOL_ESB_DPL" ? You mentioned "one byte by one byte is ok"

If it worked then it's a little bit strange because the old legacy chip won't support ESB.

Please send me your code to setup both the nRF51 and the peer chip.

Note that the old chips nRF2401A, nRF2402,nRF24E1 and nRF24E2 are not suggested for new design.

hi hung bui, Set the protocol to uesb_config.protocol = UESB_PROTOCOL_SB instead of UESB_PROTOCOL_ESB_DPL,My code Can't work.

@libra: Do you mean that you managed to solve the issue ?

Hi Hung Bui， i have found the key.main_micro_esb_wireless_uart.c

Hi Hung Bui， Thanks for your reply.But I met another problem now.I saw the blog in the articlelink text. Using app_uart_fifo replace its simple_uart, fifo.I found my project have a bug: one byte by one byte is ok.When testing string , found that the packet loss .main_micro_esb_wireless_uart.c

Hi Libra,

The provided Enhanced Shockburst library in the SDK only compatible with the Enhanced Shockburst for legacy product, not the Shockburst. 9 bit packet control can not be removed.

You would need to use the radio directly to talk with the legacy products with Shockburst. We have created a more flexible ESB library that support SB. Please have a look here. If you have a look at the source code, the modification needed to change from ESB to SB is to set the protocol to uesb_config.protocol = UESB_PROTOCOL_SB instead of UESB_PROTOCOL_ESB_DPL or UESB_PROTOCOL_ESB.

This will disable retranmission, packet control, dynamic payload, etc.
