Current consumption in deep sleep differs betwwen s112 and s132

[Greger]

I am experimenting with the Ebyte E73 module which is just a nRF52832 chip combined with capacitors, resistors and xtals. I also have the J-Link lite cortexM programmer.

Both examples below will build and run but the s132 example consumes ten times more current (approx 0.5mA) compared with the s112 example during deep sleep. The source code is the same..

nRF5_SDK_15.2.0/examples/ble_peripherial/ble_app_beacon/pca10040/s132/ses

nRF5_SDK_15.2.0/examples/ble_peripherial/ble_app_beacon/pca10040e/s112/ses

I am very curious why this is the case especially when the s112 example are assuming the use of nRF52810 and I have the nRF52832 chip.

Hi,

You should get about 0.5 mA with both examples, as both have UART logging enabled by default. You can reduce the current consumption down to about 2 μA if you disable logging by setting NRF_LOG_ENABLED to 0 in the projects sdk_config.h file.
