NRF51 with PTR5518 range problems

[tanja]

Hi friends,

I'm using a NRF51 IC with this 4.0BLE Modul PTR5518 and i have big problems with Range. As a protocoll i use gazell. In air it is possible do get some correct signals up to 6-7 m but that it don't work properly anymore. If you have a human body in between it is a disaster, you only get good signals with a range <1m. Can i somehow approve this? Please help me if you can. I'm very desperate.

Thank you in advance. Tanja

Yes I have mounted in an housing, but this makes no difference. I tested also the Module alone and it was the same result. The problem is not really the range itself, we are able to talk with the module in a range of 7-9 meters without problems (no data gets lost). The problem is if something is in between, especially a body part, like a hand which shields the module. Is it also somehow possible that the dimensions of the room especially the height, where you use it somehow can influence the range and the behavior when it is shielded?

Thank you for your answers.
