Long Story short This library for lora
Is awesome
It is the 3rd lora lib I'm tring and it is really feature rich , well coded and well documented compared to the other ones
But I've try To add AES Encription on top of it , And found a small bug ( or is it ? )
Sometime AES encription spit back null character as encrypted Data ( ie \0)
This is an issue because as soon as the transmit feature stumble
on it, it assume it is at the end of the data buffer , ( or it behave like so)
To simply demonstrate that, I'm using the Basic TX-RX demo and only doing one modification
This
int state = lora.transmit("Hello World!");
Is now this
char TXbuffer[64] = "012345678901234567890123456789012345678901234567890123456789" ;
//TXbuffer[2]=0; // uncomment to test
int state = lora.transmit(TXbuffer,64);
And as you can see on the Screenshoot,
I'm spying the RF with a SDR , and the burst are proportionaly smaller when introducting the TXbuffer[2]=0;
I've been looking into this for 3 days now , and I'v dig as deep as I could into the library , but didnt found anything looking bad
Any suggestions ?
EDIT:
Ho well
Just found that if using Byte instead of Char , the problem disappere
Type conversions issue I guess
Will have to investigate more , But the loralib is probably not the issue here
Going to bed
