Hi all,
I’m working with the RadioHead library RF95 and originally the lib allow to set address as uint8_t like you see here
bool RHReliableDatagram::sendtoWait|
(uint8_t * *buf*,
uint8_t *len*,
uint8_t *address*)
I’d like to change it and set address to uint16_t it’s easy to change it but my question is Radiohead will allow it in packet construction ? Should I only change all uint8_t address by uint16_t address ?
You will have to modify several parts of the library code to do that.
Why do you think you need more that 255 addresses?
Yep but should I only change uint8_t address and uint8_t from?
I need more than 255 because all my adresses start from 1500 and I can’t change it. The address coming from another code and I receive the address by serial and all addresses starting from 1500 this why I need uint16_t
Of course you can. Subtract 1500 and use the remainder in RadioHead.
Or use some other operation, like a lookup table, that maps 16 bit addresses to unique 8 bit addresses.
Revert back to the original address on the receiving end. People do this all the time.
Ok but if I got 1825 it’s doesn’t works and it’s possible or I can have 1925 for example.
And I can’t do minus 1800 and minus 1900 because it will result at the same address
Before you spout objections, read all of a post. Are three lines of text too many for you?
