ST25R3911B-DISCO Board receiving distance is only 10CM，HOW to set the registers and out the maximum power of 1.4W

Hi,

finding this post in the basement....

ST25R3911B-DISCO is typically operated already at its maximum power. Power is defined by the chip and by the antenna and its matching. Please refer to AN4974.

Just blasting more power into the antenna does not necessarily increase operating range.
