Hi! I have subj phone and compiled smstools from original tar. Can send sms, but can not receive, having mysterious error 4088. But PDU converter works perfect with messages from log.
So, could somebody help me: what's the right config for that case to receive messages from phone, put them to /var/spool/sms/incoming and delete from phone?



smsd.conf:
devices = GSM1 logfile = /var/log/smsd.log loglevel = 7 phonecalls = /var/spool/sms/calls incoming_utf8 = yes decode_unicode_text = yes [GSM1] device = /dev/ttyACM0 mode = new incoming = yes incoming = high report = yes send_delay = 20 baudrate = 115200 rtscts = no report_device_details = yes check_memory_method = 31 loglevel_lac_ci = 8 memory_start = 0 hangup_incoming_call = yes phonecalls = clip phonecalls_purge = yes detect_unexpected_input = yes

And so on repeating.

Thanks a lot!

Huh, can't edit my post now... O_o
So, some news: 4088 isn't error's number, it's just message number.
Also, there're troubles only with delivery status messages (that said that your message is successfully delivered to recepient's phone), regular messages parsed ok.
I can disable requesting of delivery messages on my phone, but it'll be pretty good to know if sms was successfully delivered or not.

Try with 3.1.16beta.

"Invalid first byte of PDU" was caused because there was no SMSC number. However, this number is not mandatory, and the new version accepts PDU without the number.
