Idle Mode ≈ 1.4mA average

Slave Unconnected ≈ 39mA average
Master Unconnected ≈ 1.4mA average
Master Inquiry ≈ 60mA average
Connected ≈ 5mA average
If you perform a remote Bluetooth RF “ATDH” disconnect command from any Master to the BlueRadios Slave
radio, the Slave radio will go into idle mode. You will have to either send a command to the Slave radio through its
local UART or cycle power on the radios to have it come back up in Slave mode. This was designed as if you
were communicating to the local UART on the Slave radio. Typically a Slave never sends a commanded
disconnect only the Master does. In this mode you can devise some clever power saving features like leaving the
Slave in idle mode until another event triggers the radio to go back into Slave discoverable mode. It is important to
remember a device in Idle Mode is not discoverable which has some security advantages. The same sort of
benefits can be achieved by just controlling when the radio is turned off/on again.

BlueRadios Class1 Module Power Consumptions
If in Sniff Mode, will go momentarily as low as 50uA in between processes.
ATSW21,4096,18,4096,18 settings will result in the Slave not connected ≈ 1mA average.
ATSW21,4096,18,4096,18 settings along with enabling Deep Sleep Mode will result in an unconnected
slave current draw of ≈ 350uA average.
A Master radio not in use it is better to just turn off the power completely to the radio and draw zero
current.
For the first couple of seconds before it connects to the Slave
ATSNIFF,1600,160,10,160 will result in the Slave connected ≈ 1.4mA average, with no data being sent.
This can even go as low as 0.6mA if you make the Slave not discoverable but connectable.
