Porting an example from pca10056 to pca10056e (Segger embedded studio)

[RichardHdrd]

Dear ladies and gentlemen,

I found the following page giving instructions for porting an example from pca10056 to pca10056e:

https://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.sdk5.v15.3.0%2Fnrf52811_user_guide.html

I'm currently using Segger Embedded Studio (SES), but also would have a working toolchain for using gcc via Eclipse.

The first described step (2) for porting projects is stated to be:

"In the project settings, change to device "NordicSemiconductor->nRF52811_xxaa".

I failed to find that setting (as well for SES as Eclipse), maybe someone can help me out?

Without force, I'd fairly appreciate any further specific information/hint for either eclipse/gcc and/or SES considering the announced porting process on the referenced webpage concerning the named IDEs.

Furthermore;

I used (for peripheral examples) the tiny software device S112, but now the (ble-central) example projects only offer a S140 device.

Do I have to expect problems using the software device S140 on a pca10056e project based on hardware nRF58211, are there any advices or hints on how to proceed/what must be considered?

Best regards,

software device

Hello,

There is usually not a lot of differences between 'pca10056e' configuration and a 'pca10056' one. What I usually do when porting a project like this is to first make a copy of the existing pca10056 project and rename it to pca10056e, then I open the *emProject file in a text editor and update the device specific settings and startup files. I have circled around the fields that will differ between a pca10056e and a pca10056 project in the picture below.

Best regards,

Vidar

Hello Vidar,

Thank you for your advice. Sadly, the screenshots posted with your instruction are cut off right for some parameters. Would you be so kind as to re-post with complete parameter lines (especially the left part)?

Furthermore: from youre suggested config-modification, it seems that the used softdevice gets changed from S140 to S112?

Reading several threads, I concluded, that S112 is not suited for BLE scanning:

https://devzone.nordicsemi.com/f/nordic-q-a/29707/ble-scanning-with-nrf52810-and-s112

https://devzone.nordicsemi.com/f/nordic-q-a/52897/ble-scan-on-nrf52811

As my final platform is a BM833A using nrf52811, I think that the second thread advises to go with softdevice S140?

Is there a restriction for staying with S140?

Thanks in advance for any help,

Richard

Hello Richard,

I recommend you find another pca10056e project in the SDK and use that as a reference, I wouldn't be able to fit everything in a screenshot anyway.

[RichardHdrd]

Thank you again, I will do that.

Are there any known restrictions that prohibit the combination of using pca10056e and S140 as softdevice?

[Vidar Berg]

Yes, if you need to select the either the s140 or s122 Softdevice if you want to support scanning. A table of compatible Softdevice versions and variants can be found here: SDKs and SoftDevices
