AE Cloud1 Kit I2C Read Error

I am using an AE Cloud Kit to communicate to a slave device using the RIIC I2C Framework.

Using a logic analyzer I can confirm that my device address is correct, and the R/W and ACK bit are correct when reading and writing.

The issue is when reading any register from the slave device, all I get is 0xFF's. I have tried different slave devices as well with no luck.

The code where this error happens is below. Some variables are not used as the code is still a rough draft.

ssp_err_t slave_read_current(volatile int current_in_A)
{
ssp_err_t err;
uint8_t rxtx_data[4];
uint32_t result;
uint32_t payload;
//int current_in_A;
uint32_t calculated_crc;
uint32_t read_crc;
volatile int data1;
int16_t receive_buffer[2];

err = g_sf_i2c_current.p_api->lock (g_sf_i2c_current.p_ctrl);

/* Start a current measurement. */
rxtx_data[0] = 0xAE;

err = g_sf_i2c_current.p_api->write(g_sf_i2c_current.p_ctrl, rxtx_data, 1, false, TX_WAIT_FOREVER);

if (SSP_SUCCESS != err)
{
return err;
}

/* Setup the read from address. */
err = g_sf_i2c_current.p_api->read(g_sf_i2c_current.p_ctrl, (uint8_t *)&result, 2, false, TX_WAIT_FOREVER);

if (SSP_SUCCESS != err)
{
return err;
}

tx_thread_sleep(2);

//data1 = (receive_buffer[0]<<8) | receive_buffer[1];

current_in_A = ((result * 0.000305185) * 100);

//p_fcurrent = current_in_A;

g_sf_i2c_current.p_api->unlock (g_sf_i2c_current.p_ctrl);

return SSP_SUCCESS;
}

The data from the register should be stored in &result. Any insight as to why I am only get 0xFF's would be appreciated. Thanks!
