we had same problems & chased them for weeks. If the 6350 is a rev: 2.0, you have to jump the SDA (label side) pin to (port 3) p-31 & scl to pin-30.. response is terrible - be sure to do some nop's between pages.

Do You have nRF6310 Mother board Circuit Diagram ?

Hello,

Just a heads up. This mod is for the old nRF6310 mother board with the nRF6350 version 1.0 LCD module.

The newest version of the LCD display module has these signals broken out on two dedicated pins on the module so no cluge is needed. Hookup of the pins to the I/O is reflected in the newest Dev Kit Users Guide..

I got that issue as well.

They use TWI (I2C compatible) to control the display on nRF6350. Pin 24 of the nRF51822 is defined for SCL and pin 25 is defined for SDA. (see twi_master_config.h) However, they are not connected to the I2C pin on the nRF6350 board (pin 23 and 24 at the EXTA). So you have to manually connect pin 24 of the nRF51822, which is P3.0 on the motherboard to Pin 23 on the EXTA; and pin 25 on the nRF51822(P3.1) to Pin 24 on the EXTA.

You can see the hack in the image attached.
