Conflict with LCD and BLE

[Peter Lum]

Hi
I have a HT1622 based segment LCD connected to a Nordic 52832 board via

P0.17(pin20) => HT1622_DATA
P0.18(pin21) => HT1622_WR
P0.19(pin22) => HT1622_RD
P0.20(pin23) => HT1622_CS

When I start using BLE, it hangs when I call Peripheral.begin();

I think there is a conflict but I do not know how to resolve it.
Help!
