Setting this is equivalent to setting max_size to a value of length + 1. max_length: Maximum length for string fields.For strings, this includes the terminating zero. max_size: Allocated maximum size for bytes and string fields.

The generator behaviour can be adjusted using several options, defined in the nanopb.proto file in the generator folder. The default setting is to use the smallest datatypes (least resources used). Their need is recognized automatically by C-preprocessor #if-directives in the generated. The PB_MAX_REQUIRED_FIELDS and PB_FIELD_32BIT settings allow raising some datatype limits to suit larger messages. Adds a small performance and code size penalty. PB_VALIDATE_UTF8: Check whether incoming strings are valid UTF-8 sequences.PB_CONVERT_DOUBLE_FLOAT: Convert doubles to floats for platforms that do not support 64-bit double datatype.
Only to be used when the decoder on the receiving side cannot process packed arrays, such as protobuf.js versions before 2020.
Speeds up execution and slightly decreases code size. Only supports encoding and decoding with memory buffers.
Using the -D switch on the C compiler command line.The following options can be specified in one of two ways:
