SoftDevice s140 5 nRF52840 Preview DK Issues

[rjones1951]

Hello,

I am trying to migrate to the latest S140 SoftDevice, but the migration document leaves a lot to be desired and is missing information. I've had issues running standard applications with s140_nrf52840_5.0.0-3.alpha where it just hangs in middle of nowhere (classic incompatibility between application and softdevice).

I've updated the API from the zip fie and am unable to compile. For example, BLE_GAP_ADV_MAX_SIZE is not defined but is not mentioned anywhere in the document.

The document says "sd_ble_enable() should be used to find the APP_RAM_BASE for a particular configuration" but no information on how to do this.

Can Nordic provide an actual working release with this softdevice or information on how to migrate?

Strange. I just tested this. I just did this:

The steps to compile the example:
1. Download the SDK 13 from:
   www.nordicsemi.com/.../59012
2. Extract the SDK to a location of your wish.
3. Extract the content of this zip-file to the <sdk_location>.
4. Extract the header files from the s140_nrf52840_5.0.0-3.alpha_API\include
   folder to <sdk_location>\components\softdevice\s140\headers folder.
5. Navigate to: examples\ble_central_and_peripheral\experimental\ble_app_att_mtu_throughput\pca10056\s140
6. Compile using your favorite compiler.

And it compiled without any errors or problems. Which compiler are you using?

[rjones1951]

Using IAR 8. Perhaps the. Will try again following your steps.

Hi Petter: Some more progress. I've been able to compile, link and debug and it stops in main. I am not sure what the difference was from before (maybe my overwriting the IAR project).

However, the device hangs in the following call stack:

nrf_delay_us

rtc1_stop

app_timer_init

timer_init

main

Aside from this, the peripheral examples are broken because advertising changes (so ble_advertising.c has errors in definitions). Will this be fixed or do I need to manually make the changes?

[Petter Myhre]

Problems with nrf_delay_us and IAR 8 seems to be a known problem. See this.

The peripheral examples will not work out of the box with the new libraries that comes with the S140 example. It will not be fixed. If you want full SDK support you will have to wait for a new SDK release.

Thank you. Am testing. Is power consumption impacted if Peripheral+Central is used and Central is somehow disabled (0 central links)?

[Petter Myhre]

I don't understand, how can you have peripheral+central if you have 0 central links?
