Same issue here.
B-station pcb 1.04 FW 1.09
String is learned ok , but maybe there are a limited number of characters displayed in the webpage of the device.
I find the webbrowser very slow when a OSC device is connected, sometimes only responding after reboot of the device.
I do seem to have another issue regarding sending messages, but maybe that is an user issue:
I Recieve my OSC messages OK, but when send a message, verified the addres (e.g. /SAUNA/led1 value 1), the device detects the incoming message but nothing happenes with the led to be controlled.
EDIT:
It seems that the webbrowser of the units only supports 10 characters of message length. If you reformat the message so that it is maximum 10 chars long it works. This issue is for both incoming and outgoing messages.
Not handy since TouchOSC needs the page name as leading for address string and then you easily come to 10 chars
