Archived:Cannot getting Bluetooth bit error rate on Symbian (Known Issue)
The Bluetooth bit error rate (BER) cannot be determined with Symbian C++ APIs.
The bit error rate (BER) is used to evaluate receiver performance. It is determined by comparing transmitted and received payload data and noting the difference in bits. The ratio of the erroneous bits to the total number of bits received is the BER.
Currently there is no solution. The bit error rate (BER) level for Bluetooth cannot be determined with S60/Symbian APIs.
