how to measure and monitor the signal strength

[MARTIN FR]

Hi everyone,

I am trying to monitor and measure the signal strenth variation by varying the positon of the developement kit NRF51 and i tried with the proximity example am always getting the -53dbm value only even though i keep the device very closer and i did not find any variation in the reading of the receiver signal strength can anyone suggest me what are the possible ways to broadcast the signal strength in real time and able to see in the nordic app

thank you prabhu

i can able to see the value in the Rssi somewhere around 65 to 45 only what ever i do it is showing the values between (45 to 65) but how can i increase the value of the RSSI because if i turn on the other bluetooth like from other android, it ti showing the RSSI value 89 or 92 dbm so can you tell me how cna i increase the RSSI value? and what should i do inorder to test the rssi value changes?

Hi Prabhu, So what happens if you bring the device/phone far away from the peer ? The RSSI goes to -65 and then you can't receive the advertising packet anymore ? Which Android device are you testing ?And I guess when you test with other phone the RSSI can go to -92 ? Most likely it's the issue with the phone you are working on.

Thanks for your reply actually i am working on the same android device for testing the rssi value i turned on the bluetooth conenction in the Nrf51DK and then i conenct with my phone it is always showing somewhere around 45 to 65 but IF I test the Rssi value of another bluetooth device (GIGA SET)it is always varying depending upon the postion of the giga set (mimimum 0 to maximum 95) why it is not happening with the development kit?

Hi Prab,

Please take some screenshots of what you are observing. nRF51DK from 45 to 65 and Gigaset (I couldn't find information about this) RSSI from 0 to 95. RSSI = 0 is very strange for me. Also please let me know your Android device.
