Ported NRF52840 to sandeepmistry Arduino NRF52

[Miguel]

Sir, good Morning

I ported the nrf52840 to be compatible with the sandeepmistry/arduino-nRF5: Arduino Core for Nordic Semiconductor nRF5 based boards (github.com)

It´s working very fine! I can compile many Arduino examples to NRF52840

The only problem is that the Ble Peripheral are not working! They compiles, execute, but, looks that the Softdevice not starts.

I guess that is compatibiliy version beteween the SDK used by sandeepmistry/arduino-nRF5: Arduino Core for Nordic Semiconductor nRF5 based boards (github.com) and the Softdevice that i am using, the 6.0.1

Do you have some suggestion ? If need to change the SDK version will be bad for me. If needs to change the Softdevice used for a lower version, should be good. But, wich version ? Back to the same used by sandeepmistry/arduino-nRF5: Arduino Core for Nordic Semiconductor nRF5 based boards (github.com) ? If yes, will work on NRF52840 ?

Thanks!

I already see that NRF52840 is running well the softdevice 2.0.1 (s132) very nice!

Take a look at the work Adafruit has done on the Arduino/nRF52 front. They are constantly working on the nRF52 arduino board support and last time I checked, were using the most recent soft device. There is a pretty large range of devices that works with what they've put together.

Yes, NRF52 Adafruit works!

But i am porting to Sandeepmistry!

Hello,

The only problem is that the Ble Peripheral are not working! They compiles, execute, but, looks that the Softdevice not starts.

 That is likely an issue - I do not immediately see which nRF5 SDK and SoftDevice version is used in the repository you link, but you can check this with the nRF52840 Compatibility matrix.

Do you have some suggestion ?

Back to the same used by sandeepmistry/arduino-nRF5: Arduino Core for Nordic Semiconductor nRF5 based boards (github.com) ? If yes, will work on NRF52840 ?

I am not familiar with this third-party repository nor Arduino programming, so I can not really say nor guarantee that any modifications to it would work.
What errors / behavior are you getting when you try to start the BLE peripheral examples? You say that they compile and execute but the SoftDevice is not starting. What are you seeing? Are you getting any error codes returned from the ble_stack_init function, or your call to enable the SoftDevice? Is the device resetting?

Best regards,
