What is PCA on every Nordiac BOARD?

[kunal_garg]

Actually i was working on 3 boards, nRF51422,nRF51822 & nRF52840. While executing some examples on each board i realised that each board has its specific pca hex file to be flashed/programmed in nRF Studio software(by Nordiac), like for example in nRF51822 the hex file needed are of PCA20006,for nRF51422 it's PCA10028 & for nRF51840 it's PCA10056.

Now their was an example code (C:\Users\kunal\Bluetooth lab\nRF5_SDK_11.0.0_89a8197\examples\ble_peripheral\experimental_ble_app_blinky\hex\experimental_ble_app_blinky_s130_pca10028.hex) this example as you can see is PCA10028,which is working perfectly for nRF51422 DK, but i want to run the same example on nRF51822 for which i need hex file with no. of PCA20006, which i couldn't find in major vesions of SDK'S available. So i tried to run the hex of PCA10028 on nRF51822 despite knowing it isn't compatible, and it isn't working as expected. Can anyone help me with the hex file of this code with PCA20006 hex please.

PCA20006, PCA10056, etc are board names for our development kits. So when you open a project configured for the PCA20006 and you program it onto a PCA20006 board you can expect both the pinout and chip variant to be correctly configured. See "Using the SDK with other boards" for an overview of the how these names are used in the SDK.

nRF51422 and nRF51822 are interchangeable when it comes to BLE applications. The difference is that nRF51422 is licensed for use with the ANT protocol stack. However, make sure your PCA20006 board has the same memory package as the nRF51 DK (pca10028). The DK has the 32KB RAM variant (xxAC), while some of the beacons shipped with the 16K RAM variant(xxAA). Chip overview:  nRF51822 IC revisions and variants
