Write collision for multiple reads - PIC24 I2C

I am trying to poll a CAP188 sensor so I'm sending it read commands in a while loop, but the first read works and then on the second read when I send the slave address it detects a write collision.

To test my code I am trying to read the product ID which is a known value. Any help would be appreciated, thanks!

void chipWrite(unsigned char reg, unsigned char data){ //Start bit I2C2CONbits.SEN = 1; while(I2C2CONbits.SEN); IFS3bits.MI2C2IF = 0; //Slave address bit I2C2TRN = 0b01010000; while(!IFS3bits.MI2C2IF); IFS3bits.MI2C2IF = 0; //Register address I2C2TRN = reg; while(!IFS3bits.MI2C2IF); IFS3bits.MI2C2IF = 0; //Data I2C2TRN = data; while(!IFS3bits.MI2C2IF); IFS3bits.MI2C2IF = 0; //Stop bit I2C2CONbits.PEN = 1; IFS3bits.MI2C2IF = 0; while(I2C2CONbits.PEN); } void initChip(){ CLKDIVbits.RCDIV = 0; AD1PCFG = 0x9FFC; I2C2CON = 0; TRISBbits.TRISB3 = 0; TRISBbits.TRISB2 = 0; I2C2CONbits.ACKDT = 1; I2C2BRG = 157; I2C2CONbits.I2CEN = 1; _MI2C2IF = 0; } unsigned char chipRead(unsigned char reg){ unsigned char msb = 0; while(!I2C2STATbits.P); /*start*/ I2C2CONbits.SEN = 1; while(I2C2CONbits.SEN); /*sensor address*/ I2C2TRN = 0b01010000; while(I2C2STATbits.TBF); while(I2C2STATbits.TRSTAT); while(I2C2STATbits.ACKSTAT); /*Register for reading*/ I2C2TRN = reg; while(I2C2STATbits.TBF); while(I2C2STATbits.TRSTAT); while(I2C2STATbits.ACKSTAT); /*repeated start*/ I2C2CONbits.RSEN = 1; while(I2C2CONbits.RSEN); /*Slave address with read = 1*/ I2C2TRN = 0b01010001; while(I2C2STATbits.TBF); while(I2C2STATbits.TRSTAT); while(I2C2STATbits.ACKSTAT); /*receiver enabled*/ I2C2CONbits.RCEN = 1; /*read first byte data*/ //while(!I2C2STATbits.RBF); while(I2C2CONbits.RCEN); msb = I2C2RCV; /*send nack*/ I2C2CONbits.ACKEN = 1; while(I2C1CONbits.ACKEN); /*send stop*/ I2C2CONbits.PEN = 1; while(I2C2CONbits.PEN); return msb; } int main(void) { initChip(); char key = 0b00000000; chipWrite(0x72,0xFF); chipWrite(0x2B, 0x80); chipWrite(0x26, 0xFF); while(1){ key = chipRead(0xFD); asm("nop"); if(key == 0b01010000){ asm("nop"); } else{ asm("nop"); } key = 0x00; } return 0; }
