migrating project from nrf52832 to nrf52810

[Pathum Sudarshana]

Hello, I tried to upload a simple blink sketch from pca10040 which works for nrf52832 to an nrf52810. But it didn't work. Then I tried pca10040e. It worked for nrf52810.

But I want to upload a ble_central_and_pheripheral example. But there are no pca10040e (emulated) examples. I tried to transfer a pca10040 to a pca10040e. But it didn't work.

Can you please help me with this? 

Or can you create the pca10040e version for example "ble_app_hrs_rscs_relay" ?

Thank You very much.

Hi,

See Creating your own emulated project under Developing for nRF52810 user guide in nRF5 SDK documentation. Note that the nRF52810 does not have FPU support in the CPU, so the project settings needs to be changed to use soft-float.

The ble_app_hrs_rscs_relay example requires both BLE central and peripheral role, which requires use of S132 softdevice. The nRF52810 have very limited flash and RAM sizes, so you may not be able to fit the application along with S132 softdevice, as this will take most of the available flash area.

Best regards,
Jørgen

Hi Jorgen,

Thank you for your reply.

I will test this and let you know.

Yes, the ble_app_hrs_rscs_relay example requires both BLE central and peripheral roles, But my app only advertises a few data and it will scan other devices' advertised data. So it won't take much flash.

I will let you know more after I test.

Kind Regards.

Pathum.

Dear Jorgen,

when I try to convert pca10040 to pca10040e, It says "there is no file named system_nrf52.c" after I remove the system_nrf52.c from the project.

Please Help out.

Thank you.

Hi,

Please make sure you clean/rebuild the project, and/or remove the build folder, to make sure everything is built using the correct files.

Which compiler are you using? If you are not able to resolve the error, please post your project file here.

Best regards,
Jørgen

Dear Jorgan,

I was able to solve that. But I got a new error "Cannot Download Multiple files because they overlap"

Does this happen because nrf52810 flash is small?

But it only used 20%.

Let me know what is wrong.

BTW, I only want to advertise a few data and scan other devices' advertised data. Can you suggest to me an example to start?

Kind Regards.

Looks like you have not reserved space for the softdevice in the "Sections placement macros". See Adjustment of RAM and Flash memory.

I think the example you have already started with is the best alternative, we do not have any examples for nRF52810 that does both advertising and scanning.
