How to reduce current while using BLE applications on ISP4520 #43

I tried the LoRa tx_temperature example and the idle current is just fine which is about 2.4uA. But when using the at_command example(where Nordic SoftDevice is used ) on the TX evaluation board, I get an unusual idle current (current between two advertising peaks) of 1.8mA. And I also tried other BLE peripheral examples from nRF SDK 16.0.0, the idle current is still about 1.8mA.

So could you please tell me is there an extra settings when using BLE applications on ISP4520 to reduce the idle current? (Maybe the SX1261 is not set to sleep mode correctly while using BLE applications)
