Mark MakarychevHello,
Does anyone here have any documentation or specs in regards to how much current an mDot draws in its active state? There’s a few topics here about the (deep/stop)sleep mode, ARM mbed’s site states that the mDot draws <18mA while “active”, and I found somewhere that TX/RX use about 28mA/10mA respectively, but that’s about all I could find. Doing some battery tests with the mDot working in class C mode (so no sleep and constant RX between TXs), my calculations show that the mDot draws around 70mA. Does this number sound correct?
Thanks in advance for any info!

Steve KovarikHello Mark
Page 25 in the Developers Guide at the link below give some mDOt power
consumption numbers.

Mark MakarychevUh-huh, ok, now my calculations seem much more correct. Thank you! Turns out that constantly listening in class C is quite power consuming! Do you happen to know when MultiTech will be adding class B to their mDot library and gateway firmware? Switching to class B in theory should increase my battery life by about 50%. Would be a nice optimization to have!
