Notes on Bluetooth communication with Android devices
Due to the multitude of Android based mobile phones available Bluetooth communication via
BLE
can
vary across platforms.
ATTENTION! Android versions 4.4 and earlier are unable to communicate with BLE devices (like the
PiCUS TMS 3).
Maximum number of connected sensors
The maximum number of devices that can be connected via BLE is dependent on the hardware of the
mobile phone and on the Android version used.
BLE can connect a maximum of 7 devices simultaneously. Depending on the mobile phone used, it
might be less.
ATTENTION! Other BLE devices, that are not part of the PiCUS TMS 3 System (e.g. BLE capable
smartwatches), also factor into the maximum number of simultaneous BLE connections.
When trying to connect one more sensor with the mobile phone, all previously connected PiCUS TMS
3 are shown simultaneously with all newly found ones. For not connected PiCUS TMS 3 the status line
reads
TOO MANY SENSORS!
For establishing a connection with a new PiCUS TMS 3 that currently cannot be connected, switch off
one of the other currently connected devices and press
REFRESH
.
Make sure the PiCUS TMS 3 hasn’t
been running for more than 2 minutes since switching on, because after 2 minutes without
communication the PiCUS TMS 3 turn themselves off or deactivate their Bluetooth module while in
measuring mode.
This device could not be connected
because the maximum number of
connected devices has already been
reached.
