-

i new smpp protocol usage, getting message in log below.

sending udh message...

smpp udh 0500031b0301004d00

how can convert udh message normal text (java program or tool).

udh not meant interpreted text. because contain non printable characters 0x00 or 0x01. ought decoded byte byte. more details udh here.

however if don't want complexity involved bits , bytes can instead use network capture tool tcpdump capture smpp packet , use wireshark decoding you.
