DTM +8dBm issue

Question

Hi 
 We want to set +8dBm on DTM with nRF52840 but it test fail. 
 When I set +8dBm, nRFgo Studio cannot test it due to fail in DTM code. 
 We tried SDK v14~ v15 version but it is always fail. 
 We also tried others command but some bugs in DTM code. 
 Please refer attach file and try in Nordic side. 
 Thanks.

Hi, 
 The SDK team are aware of the issue, but unfortunately, the change didn't get added to SDK 15.0.0. It will be coming in the next SDK. For now, the following workaround can be added to get +8dBm support. 
 uint32_t dtm_radio_validate(int32_t m_tx_power, uint8_t m_radio_mode)
{
 // Initializing code below is quite generic - for BLE, the values are fixed, and expressions
 // are constant. Non-constant values are essentially set in radio_prepare().
 if (!(m_tx_power == RADIO_TXPOWER_TXPOWER_0dBm ||
 m_tx_power == RADIO_TXPOWER_TXPOWER_Pos4dBm ||
 m_tx_power == RADIO_TXPOWER_TXPOWER_Neg30dBm ||
 m_tx_power == RADIO_TXPOWER_TXPOWER_Neg20dBm ||
 m_tx_power == RADIO_TXPOWER_TXPOWER_Neg16dBm ||
 m_tx_power == RADIO_TXPOWER_TXPOWER_Neg12dBm ||
 m_tx_power == RADIO_TXPOWER_TXPOWER_Neg8dBm ||
 m_tx_power == RADIO_TXPOWER_TXPOWER_Neg4dBm ||
 m_tx_power == RADIO_TXPOWER_TXPOWER_Pos3dBm ||
#ifdef NRF52840_XXAA
 m_tx_power == RADIO_TXPOWER_TXPOWER_Pos8dBm ||
#endif //NRF52840_XXAA
 m_tx_power == RADIO_TXPOWER_TXPOWER_Neg40dBm
 ) ||
