  • Hello, I am newbie to nrF52 480 chip, and i am using the beacon code in nRF5_SDK_15.3.0_59ac345 SDK. I tried to add DEVICE NAME but as soon as I added the device name, to the code and compiled, the android app (nrf Beacon) chip stop detecting the beacon from the nrF chip. I have tried reducing the manufacturer data but still behaves the same way. I will appreciate any help to resolve this I have included the sample code. Many thanks

Comment
  • Hello, I am newbie to nrF52 480 chip, and i am using the beacon code in nRF5_SDK_15.3.0_59ac345 SDK. I tried to add DEVICE NAME but as soon as I added the device name, to the code and compiled, the android app (nrf Beacon) chip stop detecting the beacon from the nrF chip. I have tried reducing the manufacturer data but still behaves the same way. I will appreciate any help to resolve this I have included the sample code. Many thanks
