    Hello, Has anyone tried these calls? I added the calls to the end of HCI_EXT_App_Init() in the HostTestApp demo project and the load hung. If I only call one of these calls, it doesn't matter which, than it works. The only usage example is in the keyfob demo, but only the HCI_EXT_SetTxPowerCmd...

    Hi Nick, Thanks for the quick response. I add the calls to the end of the HCI init function: void HCI_EXT_App_Init( uint8 task_id ) { : : HCI_EXT_SetRxGainCmd(HCI_EXT_RX_GAIN_HIGH); HCI_EXT_SetRxGainCmd(HCI_EXT_TX_POWER_4_DBM); } Nothing else was changed. The load hangs but works normally...
