Low battery led blinking TD1208

Hi all,

I'm still working on our project based on TD1208, and I want to code the EFM32 to send sigfox frame on low battery.
I have no issue with the low level detection or the sigfox frame to send.

But (there is always a but) :
When I supply the EVB (with my code on it) with a 3.1V voltage (to simulate low power), I receive my alert flag by UART, but the led is blinking (without code for that), and no SigFox frame is sent.

Is that really possible to monitor battery state using SigFox network ?
