receiving numbers bigger than unsigned long

[Anduril]

Hey there,

I know an arduino is capable of using uint16_t type variables. But how do I get them transfered within the mysensors framework? I know there are way to read int (message.getint) and long (message.getlong) for usage in void receive(), but how do I receive an uint64_t number? I couldn't find a documentation about this. But as far as I read the max payload is 25 byte, so it should fit in.

Regards,
Anduril

You can send custom data structures using:
https://github.com/mysensors/MySensors/blob/development/core/MyMessage.cpp#L230

... and pick them up using:
https://github.com/mysensors/MySensors/blob/development/core/MyMessage.cpp#L64

Thanks a lot @hek
What do I have to write for length at MyMessage& MyMessage::set(void* value, uint8_t length)? Is it 8 byte or 64 bit? Is MAX_PAYLOAD defined in byte or bit (or something else)?

64bit / 8 = 8 bytes length

well yeah thats obvious, my question was more about the specific syntax (but that was not very clear).
Which of the following do I have to use?

uint64_t value;
send(Mymessage.set(value,8);
send(Mymessage.set(value,64);
send(Mymessage.set(value,8 byte);
...

@Anduril said in receiving numbers bigger than unsigned long:

uint64_t value;
send(Mymessage.set(&value, sizeof(value) );
