Hello, I'm testing the module ATZB-RF-233-1-C but I'm not sure that the output power is maximum possible, about 19dBm.
I have written several values in PHY_TX_PWR register, but it seems that output amplifier of the module is switch off, and only works with AT86RF233 output power (4dBm). Range is too short.
Documentation that I found does not explain too much. Can you help me?
