compile error and question about SDK and SoftDevice

[jacky]

Dear Sir/Madam,

I tried to use GPIOTE and nrf_dev_gpiote at same prject on a MDK 5 project which is based on nRF5 SDK 10 and SoftDevice S110, but got this error: 

.\_build\nrf51422_xxac_s110.axf: Error: L6200E: Symbol GPIOTE_IRQHandler multiply defined (by app_gpiote_fast_detect.o and nrf_drv_gpiote.o).

By searching the forum, I read someone mentioned that SDK 11 has fixed this issue. But when I checked SDK11, it seems doesn't support S110 inside.

My question is: Is it possible to mix SDK11's nrf_gpiote code with SDK 10's GPIOTE together to solve this issue or is there any other solution?

Thanks,

Jun

Hi,

You have multiple alternatives:

• Avoid using both app_gpiote_fast_detect and nrf_drv_gpiote in the same project. You can still use app_gpiote, which use the GPIOTE driver in the low-level API.
• Merge the GPIOTE handlers, as described in this answer.
• Upgrade to SDK 11 and S130 softdevice.
• Try to backport the GPIOTE libraries from SDK 11 to SDK 10.

Best regards,
Jørgen

Hi Jorgen,

Thank you for the reply.  I want try upgrade to SDK11 and S130 softdevice. But I am a newbie, don't know how to upgrade the SDK and change the softdevice.  Could you give me a detailed description of step-by-step procedure on it?

Thanks,
