Hello,
When I include in my code (Arduino IDE) sd_power_dcdc_mode_set(NRF_POWER_DCDC_ENABLE) on E-Byte 52840 module (E73-2G4M08S1C) power consumption increases to 30mA instead of 6mA when a client connects to nRF52840. After boot consumption is 50 uA with BLE enabled and after ~25sec it goes to 30-35mA without any connections from clients and stays at this level forever.
Without sd_power_dcdc_mode_set(NRF_POWER_DCDC_ENABLE) after boot consumption is 50 uA with BLE enabled and it stays the same for hours. When a client connects it goes to 6-6.5mA, after a client disconnects it goes back to ~50 uA.
Is it module related issue?
