With s110 v8 code is not running and not even led is on. I tested in debug mode it is not running. I just add simple LEDs in main, but these leds are not getting on.

Thanks it programmed. I do not know how to test this code can you guide me or any document for testing.

Check your S110 softdevice release notes, that size and RAM needs are stated in it, use it to verify your settings.

I change Rom1 : start 0x14000, size:0x2B000 and RAM1: 0x20003000, 0x5000 and in j link RAM algorithm : start: 0x2000000, s:0x2000.
My device is nrf51822 EK-PCA10001 v2.2.0 2014.10 will it work for this code OR i need to change.

For s110v8 also giving same error.

Lets start with the S110 first and then get it working and then more to the S130. Make sure that the RAM and ROM settings in keil match the release notes for the specific softdevice. For example you can see this devzone.nordicsemi.com/.../ , but look at the release notes.

Hi, I taken sdk8.1 and softdevice s130v1, i can able to compile properly if i try to load application it takes it giving error failed and **JLink Warning: T-bit of XPSR is 0 but should be 1. Changed to 1 in keil. So i changes the ram size into 0x5000 in jlink settings. then also it giving same error. My device is nrf51822 EK-PCA10001 v2.2.0 2014.10 will it work for this code OR i need to change. What type of device configuration i need to do it , could you please advice me.

The sdk-8-support branch is the latest and right code base to use. Can you switch to the github.com/.../sdk-8-support version, only revision 2 nRF51 ICs or greater are supported.

Revision 1 ICs are not supported, please look at the compatibility matrix for the nRF51 IC, additionally if you are using a revision 2 IC (which is 16K or RAM), make sure you adjust the ROM and RAM settings for keil/your toolchain accordingly.

I did again by re flashing soft device and hex file, now also same thing happens as previous, leds are ON only on one board not in other one. I flash same application into the both boards or do i need to flash different application to each board? can share me soft device link for this.

Trond Einar Snekvik — Fri, 01 Apr 2016 08:31:00 GMT

So the buttons one one of the boards are able to trigger the LED's on both boards, but the other way around, nothing happens? Could you try reflashing both the softdevice and the working application on both boards?

Hi Trond, Thank for reply, I did same what you suggested. i complied the mesh led code and programmed into pca10001 EV kit (same two boards) along with softdevice s110_nrf51822_7.0.0_softdevice. If i press button on one board LED may ON other board(I don't Know flow of application). But for me LEDs are ON in same board and No LEDs are ON on other boards. if i press button on other board no state changes in LEDs on both the boards. Is any thing mistake i did please help me it is truly urgent or please share document for testing.

I am waiting for your fast reply........!

Hi, if you have a devkit (with marking PCA10028 or PCA10001), you can test functionality with button presses. The main-file in the example has a GPIOTE_IRQHandler() function which will be called when you press a button on your devkit (if it's compiled in - note the #ifdef's surrounding it). You should be able to control the leds on your dongles and kits. If you only have dongles, you can do the same thing with a BLE-enabled smart phone, connecting to the advertisements with the nordic-app, and interacting with the GATT server

Hi Trond,

Thanks for reply,

Can you guide me how to test this code, in LED_MESH application. Any testing procedure or document to test, can you share me the things.

Please help me on this.

Hi there,

The files you're missing are part of the nRF5 SDK. If you're in the master branch, you need the nRF51 SDK v7.2 (zip-file). The Readme in the repository guides you through initial setup:

Getting started

The framework supports both nRF51 SDK 6.x.x and nRF51 SDK 7.x.x. Since the structure of the SDK changed between these versions, you have to clone the repo differently based on which version you utilize.

If you’re using 6.x.x, clone the repository into < SDK6-folder >/nRF51822/boards/PCA10001/S110/< Project-folder >.

The SDK 7.x.x projects utilizes the non-pack version of the SDK, available at Nordic Semiconductor’s developer portal. Clone this repo into < SDK7-folder >/examples/< Project-folder >.

This will ensure that all references to the SDK are correctly placed, so that you don’t have to change all references to the SDK in the project files. If you still want to clone the repo into a different folder than suggested, you need to change the location of all the files under the Lib group in Keil uVision, in addition to the include paths under the menu Target options → C/C++ → Include Paths.

The nRF51-ble-bcast-mesh is a flooding mesh, which allows you to share a set of data values across any number of nRF51-devices, as long as they are close enough to each other to form a network. The Readme explains the basics of the framework, and links to some more detailed descriptions in the /docs/ folder. There are also examples available under nRF51/examples, displaying simple usage.

Have you downloaded the SDK v7.x.x from the Nordic Semiconductor Developer Page?
