We have a issue about nRF9161 on our custom board.
we flash hex our board. It doesn't work very well. sometimess it work and consume about 90mA current. sometimes board consume about 40mA and it doesn't work. We noticed that when our board works 57.pin ( VIO ) is 1.8Volt.
When it doesn't work VIO is 0 volt. Same card, same firmware, VIO pin have no connection.
same hex work very well in nRF9161DK.
what do you prefer us? what should we check about it?
