RX TX modules - intermitent communication

[ruijc]

Hi dhouston,

You are correct, these are FSK modules and they output automatically the data, that's why i had those questions made about the pulsin

However, you really need the first bit of each reception to trigger an interrupt to assure that you catch each byte.

True, but in this case i'm starting with a very simple Loop ( both RX and TX ). For now i'm not thinking Interrupts. Just need to get the data flowing correctly first and therefor i'm using just this :

TX

tx:
debug "ok", dec value dig 3, dec value dig 2, dec value dig 1, dec value dig 0
gosub getvalue
goto tx:

RX

rec:
debugin [wait ("ok"),dec4 MYDATA]      
lcdout cl,row4, "received - ",DEC MYDATA
goto REC

Still, i get the same simptoms...sometimes receive all digits, sometimes none, sometimes just one or two

Thanks again for all your help.
