Custom BLE service on nRF52840 (pca10056) with nRF5 SDK 15.2

[Ken_Hu]

Since APIs have changed as new nRF5 SDKs have released from time to time, it is not clear how custom service can be implemented on BLE peripheral for nRF52840 (pca10056) S140 Soft Device. I am using Nordic nRF52840 Development Kit with SEGGER Embedded Studio. Please help!

Hi.

There is a great tutorial on this subject found on GitHub here, check it out!

It is for SDK 15.0, but it should also work for 15.2.

Best regards,

Andreas

I encounter an issue for the RAM allocation while following the tutorial. May I know what's the proper ram_start and ram_size to be used in that tutorial for a pca10056? (Since the RAM size is different)

Please check out our RAM and Flash memory adjustment guide here on DevZone for the various RAM_start and RAM_size values, and how to set them. If you need further support, please create a support ticket of your own.

Best regards,

Simon
