Has anyone practical experience with the range achieved using BLE with a KW3x/4x and in-circuit antenna (as on the freedom boards)?
The programmable transmitter output power is up to 3.5dBm, which corresponds to about 2.2mW and BLE class 3 max. 1mW) is recommended for 1m range. BLE class 2 (max. 2.5mW) is recommended for up to 10m range.
This means that it should be able to do class 3 and class 2, up to maybe 7m.
Can this be confirmed as practical or can it do longer distances or is limited to less ?
