CC2591: CC2591+CC2430

Part Number: CC2591

RF: Zigbee

Power: 20dbm

Question: After a month of use, the transmission distance becomes closer,  150 meters => 20 meters

    Referring to our test result ,we  can confirm that there are some problems with the chip "cc2591" . but it's not completely broken, it affects transmitting performance  ( because we don't have the test equipment, so we don't know if the receiving performance was broken too)

We need to know the actual problems ,so we need you help to carry out the test on the equipment.


Also we hope that according to the test result , you can give us the possible cause of the problem.
