What are the checkpoints to successfully power HSE32 TCXO?

Some facts:LoRaWAN_Init reports no errors, seems that calibration went through OK...?(RadioError result = 0)After trying out different power-modes(LDO/SMPS) and trying to put the Radio into StandBy(to measure the voltage on TCXO_VDD pin) RadioError b...

I am using the NUCLEO-WL55JC1 board to transmit LoRa 868MHz using low-power mode (14dBm). However, when I measure the signal in a noise free radio lab, the received signal power is incredibly low - has anyone encountered something similar?

Details:TX Power on Board: 14dBm (LP)Omnidirectional TX antenna (on board): 2dBiDirectional RX antenna (LPDA): 4dBiDistance: 0.5m free space with minimal interference in labFrequency: 868MHzFSPL (868MHz @ 0.5m) = -25dBExpected P_ in RX: -5dBmMeasure...
