mDot working current in deep sleep mode

[Ya Li]

I test the working current of MTDOT-915-X1-SMA and MTDOT-868-X1-SMA in deep sleep mode respectively using the “mdot_sleep” code and I find some problem.
The working current of MTDOT-915-X1-SMA in deep sleep mode is about 30uA, but the working current of MTDOT-868-X1-SMA is about 500uA.
I wonder why there is such a difference between these two products. Is there any problem with the MTDOT-868-X1-SMA or I use it uncorrectly?

Ya Li,

Are you running the same code on both devices?

We had an issue on early mDots where the SPI select line to the LoRa radio would float up which woke up the radio and caused it to draw more current.

Please open a portal case at http://support.multitech.com/ so we can get more info and get this issue taken care of.

Cheers,

Mike
