BLE is not working on N51822

[Rajesh]

Hi,

I have develop my firmware on on nRF51DK which has n51422 chip.

But my actual hardware has n51822 chip.

So my firmware is working on development board (nRF51DK).

But it is not working on my actual hardware (n51822).

My actual hardware has n51822 QFAAC0 as per infocenter.nordicsemi.com/.../... this document it is rev1 chip

But nRF51DK has N51422QFACA1 which look like rev3 chip for that I have used S110 v8 softdevice.

Can you please help me to make it working?

Do I need to make any changes in my firmware?

Do I need to use different soft-device files for n51822 as compare to nRF51DK?

Thanks

Rajesh

I asked a very similar question the other day: devzone.nordicsemi.com/.../

It seems like the differences between nRF51822 and nRF51422 are minimal, as long as you don't use a softdevice with ANT you should be able to go from one to the other with no changes. (note, it's nRF51822 not "n51822")

Better question: what is your actual hardware? You'd need to give a bit more info, such as the exact markings on your actual hardware chip (and maybe the HWID), also SDK version, softdevice version, etc. Is it a rev2 or rev3 chip? (If rev2, you may need older SDK) Does it have the same flash and RAM size as the nRF51DK? (If not, you'd have to adjust the linker file) How does your firmware not work? Last but not least, can you run an unmodified SDK example on your actual hardware?
