Fona 808 shield resets on arduino connection

by wasio on Fri Nov 24, 2017 11:52 am

Hi all
I cannot use my arduino uno as a driver for FONA 808 schield.
Each time I press reset button or upload the test sketch to the board, the shield seems to reboot or to perform a hard reset.
I use FONAtest.ino from Examples section.

-> So first the blue Net LED blinks once or twice
-> Immediately after that all LEDs except charging/charging-done LEDS are off for approx. 30 seconds. During this time arduino tries to establish the serial communication to the FONA and alwas runs into time out throwing the message " <--- Couldn't find FONA".
-> When FONA is up and running, the UNO is already left into infinite loop ( while (1); )

I soldered all header pins and shortened 3.5V power to Vio Plug on the board -> picture attached
Any help appeciated
