https://devzone.nordicsemi.com/f/nordic-q-a/119919/how-to-flash-esb-examples-on-nrf52840-usb-dongleI am trying to flash the Enhanced ShockBurst (ESB) example on an nRF52840 USB Dongle (PCA10059) . Since the ESB example is originally designed for the PCA10056 (nRF52840 DK) , I have modified the Makefile and memory configuration accordingly.

If application does not start, then we need to see if you have overwritten the bootloader with usb support needed on the dongle, if your application starts and you have issues with the esb specific communication, then if would help if know if there are any errors on it. Are you running the example out of the box? I mean no changes to the sources apart from those Makefile and linker file changes? Which example are you running exactly? ptx or prx?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/528043?ContentTypeID=1Wed, 19 Mar 2025 15:00:29 GMT137ad170-7792-4731-bb38-c0d22fbe4515:c64287fc-9122-4d1f-b47c-35ead757d120Abhishek embedded<p>hi susheel nuguru, thanks for the reply<br />yes i am compiling with gcc, able get button response and blinking of led but not able do the esb communication</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/528037?ContentTypeID=1Wed, 19 Mar 2025 14:44:47 GMT137ad170-7792-4731-bb38-c0d22fbe4515:1a795e78-0a49-43f6-808b-bda392b9e74aSusheel Nuguru<p>assuming that you are compiling with gcc and not in SES, If you have changed both CFLAGS, ASMFLAGS and the linker file.should be enought to make that project work for pca10059 dongle.</p><div style="clear:both;"></div>
