Use of GPIO16 to 19 on BGS5 | Thales IoT Developer Community

June 26, 2014 - 2:21am, 3095 views

Hello, I have a question about the use of GPIO16-19 pins on BGS5. When I configure them via AT^SCPIN=1,16,0 as inputs, and then read the value using AT^SGIO=16, I always get 1 no matter what level is on the pin. When I configure AT^SCPIN=1,17,1,0 as output, and then set it high by AT^SSIO=17,1 the pin stays at 0V. I tried using other GPIOs and they seem to work normally. Is it a firmware bug or am I doing something wrong?
