Newbie to Nordic nrf51822

[tharun]

hi, As a ambitious tech lover i bought BLE400 nrf51822 motherboard. I downloaded SDK 11.0, keil and nrfgo. I started programming based on the Nordic developer Zone. I first did the blinky example successfully and then i tried the ble_app_uart example [https://devzone.nordicsemi.com/tutorials/2/] but I dont notice LED1 blinking on the board approximately every 2 seconds as instructed. I tried to flash many more examples of ble_peripheral from the SDK but i failed to find nrf51822 advertising. Hope you will help me to fix this and give a proper guide. Thanks in advance.

Hi,

The tutorial is based on the nordic development kit.

This board has a different pinout from the one you are using, I think LED 1 is mapped to P19 on your board, this means that you would have to change the pin mappings. You can find a guide to this in this link.

Best regards,

Øyvind

I started working on BLE400 motherboard from this tutorial[http://morf.lv/modules.php?name=tutorials&lasit=35]. It was a good tutorial and from there i downloaded the BLE400 BSP. I added them to my SDK file as he said. When i looked into the code, he had done the Led mapping well and I hope this is fine for advertising too. Or if you had a glance at the that code he created please guide me whether i should add some code along with that for advertising.

Did you flash the SoftDevice before trying the examples with BLE?

I was trying to build and flash the program using .uvprojx file from the SDK using keil 5 and i failed. Now I tried to flash the hex file directly using nRFgo Studio and i successfully executed the tutorial [https://devzone.nordicsemi.com/tutorials/4/]. What do you think about this issue?

I'm looking into updating the tutorial right now. I think you might have had issues with the SoftDevice not being programmed before programming the chip, or wrong IRAM/IROM settings.
