Testing a little bit with the nRF511822 and Power Kit. After a little testing, I changed my application a bit and wanted to flash it into DK (via Keil) and it didn't directly give me any faults but the application on the DK didn't changed... :( More specific, I made 7.5 ms the min and max connection interval choice for a while, to test more easily. But now I want to measure power with 100 ms connection interval to compare and to do so I changed the min in application back to 100 ms (and max to 200 ms). But application still does 7.5 ms as default and changes back to 7.5 ms to quick after changing to 100 ms by hand so I really want to change the application. Is there any way to do this with Power Kit on it or do I really have to solder my DK back to normal behavior just for this?
Thanks in advance for helping!!
If you want to flash firmware to the DK, while the PPK is connect to the DK, you can set the PKK switch COM (SW3) to EXT. This will disconnect the PPK from the SEGGER J-Link on the nRF5x DK. More information can be found on this page.
Thanks for helping :) I found the switch but it appears to be protected by some kind of "sticker" or something. I can't seem to set the switch because of it lying on top of it and it doesn't seem to be a normal sticker because I can't get it of so easily. Is this just some sort of protection or ... ?
Nevermind, got it of, nothing blew up and I think it worked. Thanks again! :)
Great you got it working : ) Yes, these types of stickers can be a little tricky to get off. Note that if you later want to remove the PPK, you don't have to solder the SB9-bridge to get the DK back in "normal behavior", you can simple just put a jumper cable or a jumper connector(link1,link2) on the P22 connector(labeled nRF current measurement on the DK)
Ok great, thanks :)
