I am trying to get two components to work on the same Raspberry Pi:
1. an RPI Sigfox board: http://yadom.fr/carte-rpisigfox.html
2. a Witty 2 power management board: http://www.uugear.com/product/wittypi2/
They are both mounted on top of each other on my Raspberry 3.
Each board works well when tested independently. However, they have conflicting requirements:
- the sigfox board requires to disable the console on the serial port (via raspi-config). This effectively turns down the TXD gpio (which becomes 0 in gpio readall)
- the witty 2 requires the TXD pin to be pulled up (this is not mentioned in the documentation but has been mentioned by the support team)
As a consequence, I can have either one of the two boards work, but not the two at the same time.
Is there any chance I could get this to work? Is it possible to disable the console on the serial port while maintaining the TXD up?
As an alternative, the witty 2 accepts the TXD to be down for a few seconds (which I could use to send a message on sigfox) so if there is a way to disable/enable the console on serial port via software without a reboot, that could work too.
Finally, do I stand a chance to have better luck with a different Sigfox board such as this one, or is this going to be a common pattern?

Thanks for your help!
