I'm attaching a cc2541em to a battery-powered smartrf05bb.
There is no jumper on the board present. EM selection switch is in SOC/TRX position.
I attach my Ammeter to P7 and switch on the board.
However, in sleep mode I do not obtain 1 uA. In fact, I see 0.2mA.
Instead, if moving EM selection switch to MSP position, I obtain 0.08mA. Just being curious why this happens. Datasheet says it should by SOC/TRX.
By removing the cc2451em from the battery board and powering in other manners, I obtain the desired value in the Ammeter.
My goal is obviously to see my 1uA while the node is powered by smartRF05BB! :)
So, I'm omitting something, please let me know your thoughts!

In case no one answered this question yet.
I think that the excessive power consumption you'r measuring is drawn from the on-board SPI flash (25PE20VP),
which is not properly configured. Refer to swru209b Appendix A.4 (last page in schematic section) for pinout.
You may also solder it out just to prove a point.
Thank you for marking the thread as answered if your question was answered :)
