Recent security updates in Android OS caused the PFDev-TI Data Monitor (previously LES100 Data Monitor) to be unable to detect DEV-IN-BLE-TI/LES100 devices. Updates to both the PFDEV-TI Data Monitor mobile application and the PCB firmware, which resolves this issue, are now available.

*Note that this issue is only seen on mobile devices running Android 9 OS and that devices running older Android OS should still be functioning properly.* 

Please download and install the most up-to-date version of the PFDEV-TI Data Monitor in the google play store. Additionally, update the DEV-IN-BLE-TI device firmware by following the "Flashing HEX Files to the DEV-IN-BLE-TI CC2650 IC" section in the kit user guide. These documents can be found in the additional resources section.

Thank you for your patience and understanding while we worked to resolve this issue. Please let us know if you have any issues and we would be glad to assist you.

Fully powered by PowerFilm’s Indoor Light Series solar, the Indoor Solar Development Kit with TI BLE is a wireless sensing module that collects data from a variety of sensors and sends it to a connected mobile device via Bluetooth Low Energy (BLE). 


Ideal for indoor environments, the DEV-IN-BLE-TI kit uses a nano-power energy harvester to operate down to 200 lux and below. The integrated power management features battery charging with over/under voltage protection and a regulated output voltage rail. Compatible storage elements include Lithium-based rechargeable batteries, thin-film batteries, and supercapacitors.


This development kit is meant to be the first building block of any IoT sensing project or idea. The wireless MCU is broken out, so additional sensors and components can be added easily. This open-source design accelerates the development process by making solar power simple.
