We are using RV50 modems to send SMS for our project.
ALEOS version 4.9.0.
We used AT commands to send SMS through the serial port.
When we send some characters like “@” or “$” they are changed in “¡” and “¤”.
I think this is an encoding problem UTF-8 vs GSM 03.38 but I don’t know how to solve the problem.
We try to use AT command SMSM2M and SMSM2M_8.
Some message are also cut buy the modem if I send the message “TOKYO” I only receive “TOK”.
If I send the same SMS to a phone no problem.
Thank you in advance if you have any informations.
