With port 1 or 125 it's the same for the downlink

For the uplink with  
msg.payload : string[12]

"EQoAEwBVIAU="  
and with a node64 i receive this :  
06/03/2024 15:40:40[noeud: debug 122](http://bpipers.freeboxos.fr:28800/#)v3/pilotage-chauffages@ttn/devices/eui-70b3d5e75e0162f9/up : msg.payload : buffer[8]

[17, 10, 0, 19, 0, 85, 32, 5]

In fact, to put it simply, I'm looking to translate Base64 into text

like that : "Ym9uam91cg==" = "Bonjour" with a nodered

A base64 node does that

Or in a function node:

```auto
msg.payload = Buffer.from(msg.payload, 'base64').toString()
return msg

```

e.g:

Unfortunately, as i have said already, that data is NOT a string
