nRF52 ESB RF (Enhanced Shockburst) SDK

[Adam Sillye]

I am trying to use Enhanced Shockburst RF protocol for the new nRF52 chip. I did not found it in the current nRF52 SDK 0.9.2, and I took a brave move to use the files and binaries from the 51 series SDK (9.0.0).

After moving around the files to be in the proper folders, Keil compiled and linked the esb_ptx_prx example project, and managed to download it to the board (PCA10040) without any errors. I haven't made any change in the actual example code.

When run it the first ESB call (nrf_esb_init) never returns, it does not return true/false... It seems that the linking is ok, there is no misalign on the stack. (I was able to debug into the the library binary and seemingly many nrf_..._init functions passing correctly, but stops at the nrf_pm_set_dyn_ack_status)

Is ESB supported with nRF52? Will the ESB appear in the future SDK versions?

Hi,

nrf_esb and nrf_gzll are currently not included in the beta release of the nRF52 SDK, but I tested the micro-esb library with the nRF52 and it's working with little/no changes, you just need to setup the project correct. github.com/.../nrf51-micro-esb

Cheers, Håkon

Hi,

Thanks for the comment. The link points to Micro-ESB, a simplified version of ESB that has the source too. Downloaded, worked well after setting the correct nRF52 header files.

Hi Adam

It is good to hear that the micro-ESB libraries are working well on the nRF52.

There will be an official ESB library in the nRF52 SDK eventually, and it is possible that this will be based on the micro-ESB, and not the current ESB implementation in the nRF51 SDK.

Did you manage to use prx on nRF52? I succesfully used ptx (nrf52) ---> prx (nrf51), but when trying ptx(nrf52) ----> prx(nrf52) uesb_event_handler is not called.

Sorry for the slow response, I haven't been in the DZ for a while. Did you try the new ESB library in SDK v11? It has been thoroughly tested with both the nRF51 and the nRF52.
