According to CYPRESS's home page, the range(meters, Los) mean 50m.

So, we think that these modules belong to class 1, right?

Hello Yocchi,

These two modules are Bluetooth Low Energy modules which has a maximum TX output power of +3 dBm. Based on the TX output power, it comes under Class 2. But because it is a BLE module it supports a maximum operating range of 50m.

Hello Sayani-san,

Thank you very much for your help.

If max TX output power is +3dBm, the output power is  about 2mW according to below equation.

W=1mW x 10^(3/10)=2mW

I agree with you.

Best regards,
