Maybe use it to display motivational messages to quit smoking , I d buy it

@ToSa thank you ...u saved my rpi;)

Can anyone pls help on this ...I'm about to eat the raspberry

Hi there again

A quick question @jka I used the 1.4 branch on both arduino and rpi and all I get o rpi are messed up messages with crc errors, can u point me a direction on what I do wrong?

Thanx
G

@hek

hi there,

nagging time ...did all that (unsigned char on both ends arduino and rpi) but all i get in my rpi is below

any ideas?!!

thanx
G

im not able to evaluate it but if the description is accurate u might want to have a look

cheers

please excuse the frivolity

u mean like this both on arduino and Pi?

// The message structure
typedef struct {
unsigned char crc; // uint8_t crc; // 8 bits crc
unsigned char version; // (3 bits) protocol version
unsigned char binary; // (1 bit). Data is binary and should be encoded when sent to sensor net gateway
unsigned char from; // 8 bits. RadioId of sender node
unsigned char to; // 8 bits. RadioId of destination node
unsigned char last; // 8 bits. RadioId of last node this message passed
unsigned char childId; // 8 bits. Up to MAX_CHILD_DEVICES child sensors per radioId
unsigned char messageType; // (4 bits). Type of message. See messageType
unsigned char type; // 8 bits. variableType or deviceType depending on messageType
} header_s;

@hek ooooooh, I thought it was already done in the 1.4 branch... Silly me.

Thanx

dont know if this should be on new subject but spare me this one

i recompiled both arduino and rpi part with 1.4 branch

but i get on the RPi side CRC errors

also changed the Data Rate = 1MBPS on arduino to match the RPI preet

any ideas?

thanx a mil
