I want to use P0.10 instead of P0.13.
Please be more descriptive in your query.
Also please search in the forum first to see if you can get the answers to some most asked questions.
There is no DK Nr52810 right ?
you are right, you can simulate everything for nRF52810 on a nRF52832 DK (PCA10040)
I don't want to tinker the DK. I have custom board. Schematics. I can't send but it's very straight.
great. Hope you make it work.
What do you mean?
What do you mean?
you said that you have a custom board with schematics that you cannot send, so I am guessing that you know how to modify that.
Now the advertising is stopping after detection.
After pin detection the code is stuck some where. Do you have any solution for this?. This is my code.
