We are evaluating range problem in of our zigbee products
For setting the Transmit Power we are using the below API and for enabling external PA we are configuring the below GPIOs
vInitialiseApp ();
// Set Power to 4dBm
eAppApiPlmeSet(PHY_PIB_ATTR_TX_POWER, 4);
/* Initialise output PA */
GPIO_PinInit(GPIO, APP_BOARD_TEST_GPIO_PORT, 0, &pa_config);
GPIO_PinInit(GPIO, APP_BOARD_TEST_GPIO_PORT, 4, &pa_config);
GPIO_WritePinOutput(GPIO, APP_BOARD_TEST_GPIO_PORT, 0, 0);
GPIO_WritePinOutput(GPIO, APP_BOARD_TEST_GPIO_PORT, 4, 1);
But we are not seeing any range improvement with the above configuration.
Are we missing any other settings /API invocations ?
Please clarify
