does this help?
does your SIM OK to send SMS?
Have you tried other SIM card or other operator on this WP76 module?
Hi @jyijyi ,
NOW I can use SMS command but I have other question about
If I use " AT+CMGS=xx\r\n" then sometimes I will get error " +CMS error:304"
I don’t know why can you tell me?
do yo find problem in text mode instead of PDU mode?
error 304 means invalid PDU mode parameter…
I found this error in PDU mode.
Does it mean that can’t use in PDU mode?
you say that you get this error only sometimes, could it be some network issue?
I think it is command error, because I try to use “AT+CMGS=xx\r” then I didn’t get " +CMS error:304".
So my question is that the command can’t use “LF<\n>” ?
I use \r for all the AT commands
