test programs: use printf %d format for codec parameters Even though all codec params (both FR and EFR) are small unsigned integers, we use signed int16_t data type for both, for interface reasons: in the case of FR it's the gsm_signal type of libgsm, and in the case of EFR it's the Word16 type of ETSI codec guts. Therefore, the correct printf format is %d, not %u, when the objective is to see what's in the variables (what the compiler sees) and catch any bugs.
