Topic: Mkr1400 dont send SMS with only battery (Read 619 times) previous topic - next topic

I have a small project with an Mkr1400 and ADXL345
When the MKR intercept an interrupt from accelerometer one SMS is sent to my cell phone.

The project works fine when i debug with USB Cable plus LiO o(via Arduino IDE) but if i plug
only the LiPo Battery the Mkr dont send SMS

Any suggestions???
Thanks
Luca

Hi @c1p81,

Could you please share the sketch you are using.

this is my sketch
it'a only a proof of concept made by cut and paste
the idea is sending an SMS when the MKR receive an interrupt from ADXL345

the sketch works fine when i debug inside IDE but dont work when i disconnect the microUSB
powering only via LiPo

thanks in advance
Luca
