nrf51822 : problem on another electronic card

[Martin22]

Hi !

I'm developing a bluetooth low energy service using the nordic evaluation kit and following the ble_lbs example. It works, but when I load the code on an other electronic card using the nrf51822 module too, i can't detect the device with my phone. I have changed the main.c and removed all parts that i can't use on my card such as button and led.. I have changed the PCA10001.h and adapted the PIN declaration.

Did i miss a step to adapte my code ?

I think @Ngyuen might be on to something here. Are you able to detect anything if you place the phone on top of the board or vice versa? Do you have an oscilloscope? Could you probe on the power supply on your board and verify that it looks as expected? Does the external 16 MHz start up? You should also scope on the VDD_PA pin on the board. This should go up to 1.8 V when the board is actually transmitting. If there's nothing there, it's not transmitting anything.

How have you implemented the radio and antenna circuitry? Could you upload a screen shot of this part of the design?
