RN131 draws 50mA sleeping

Hi, when running the RN131 in sleep mode Im reading 50mA of current. Ive issolated my circuit from the possible cause.

Any ideas why its drawing so much.

Im not using boost, Im only using TX RX pins.

Thanks

Hi, using a pull down did not work, still drawing 50mA.

When I force RESET on the module low, the power drops to around 3mA which is what I expected with the MPU running.

thanks
