SYS_CTRL is typically connected to an ON/OFF push button. If power is present from the
battery and/or charger, and software has placed the device in the Power OFF mode,
a long button press (SYS_CTRL held high for 20 ms) boots the device. Once the module is
booted, SYS_CTRL acts like a standard PIO. The function of SYS_CTRL can be configured.
Please refer to the UART Command Manual for the SYS_CTRL function once the module is
booted.
To Wake-Up an external processor on Connection, PIOs can be used. With GPIO control
disabled, PIOs will go High when a Bluetooth connection is established. Please refer to the
UART command line manual for more details.
ESD protection
The module has no supplementary ESD protection other than that provided by the IC within
the module. The Bluetooth IC ESD protection is limited to:
Human Body Model Contact Discharge per ANSI/ESDA/JEDEC JS-001
Class 2 - 2kV (all pins except CHG_EXT; CHG_EXT rated at 1kV)
Machine Model Contact Discharge per JEDEC/EIA JESD22-A115
200V (all pins)
Charged Device Model Contact Discharge per JEDEC/EIA JESD22-C101
Class II - 200V (all pins)
It is recommended to adding supplementary ESD protection to externally available interfaces
in the end application.
