Hi,

Check the following.

  1. Ground of both Raspberry Pi and PIC should be made common.
  2. Baud rate, Parity Bits, Number of bits should be same
  3. Raspberry Pi output is 3.3V while PIC is 5V (3.3V PIC is also available). So you should use level shifting to prevent any possible damages to Raspberry Pi.
