Ble examples dont work

[Bartosz]

Hello,

I have a problem with ble_peripheral examples.

• Im using Embedded Studio V3.40 and I setup it like in this tutorial: devzone.nordicsemi.com/.../segger-embedded-studio-a-cross-platform-ide  - (../../../../../../components/device; FLASH_START=0x1B000 SRAM_START=0x20001870; NO_VTOR_CONFIG; s130_nrf51_2.0.1_softdevice.hex, modified thumb_crt0.s and flash_placement.xml )
• SDK: nRF5_SDK_12.3.0_d7731ad
• Board: nrf51422 DK (pca10028)
• Windows 7

Blinky example (from peripheral) works fine. I was trying pure blinky example and with a SoftDevice and everything looks ok (leds are blinking). I have a problem with every examples from ble_peripheral compiled and run from Embedded Studio. Hex files works good.

When i try ...\examples\ble_peripheral\ble_app_template\pca10028\s130\arm5_no_packs and i will start debug i can see that program stops at SVCALL(SD_SOFTDEVICE_ENABLE, uint32_t, sd_softdevice_enable(nrf_clock_lf_cfg_t const * p_clock_lf_cfg, nrf_fault_handler_t fault_handler));.

I add that I'm verry begginer. Anyone can help me?

Thank You

It's not straight forward to port the BLE examples to SES. I can give you an example from SDK 12.3.0 based on ble_app_hrs which is already ported to SES to work with nRF51, then you can have a look and use this as a template for your project. Here it is: nRF5_SDK_12.3.0_SES_51_example.zip

So any particular reason for starting with such old devices, and old SDK?

Does SDK v12.3.0 come with SES projects?

For nRF51, it should be possible to get some basic projects working using the free version of Keil ...

Im sorry for not responding so long and thank you for example.
When i debug this example im getting message:

SDH:WARNING:sd_ble_enable: RAM start should be adjusted to 0x20001fe8
SDH:WARNING:RAM size should be adjusted to 0x6018
APP:INFO:Heart Rate Sensor Start!
APP:INFO:Fast Advertising

I was trying change RAM_START and RAM_SIZE according to this video ( https://www.youtube.com/watch?v=uP8RYgYGRvI&hd=1&feature=youtu.be&t=254 ) but nothing changed and message is still printed.
