1. The HS_Startup_Time has been measured according to the “Bringing up the BlueNRG-1 device” (AN4818). The
HS_Startup_Time parameter is important because it permits minimization of the current consumption. A value that is too
short prevents the SPBTLE-1S from correctly sending/receiving packets. Users should set the typical value as indicated in
Table 3. Radio features .

Current consumption values has been taken using the “BlueNRG current consumption estimation tool”, configured
to match the SPBTLE-1S configuration.
The tool is available on ST.com at:

Reported values have been taken configuring the tool as shown in the follow figure:
