I am using RV50 on a out-door screen project. The MCU controls RV50 by serial port. RV50 was updated to newest version of firmware.
I send SMS to report status
AT*SMSM2M=“1234555523 voltage=12.487V output=[good] display on”
What I got from my phone is
voltage=12.487V output=ÄgoodN display on
The ‘[’ was replcaed by ‘Ä’ and ‘]’ was replaced by “~ above N” (I can’t input the char)
How could I set the RV50 to send pure ascii SMS?
If I want a “New Line” in SMS, what should I do? I tried to incert ‘\x0A’ in SMS but got “ERROR”.
One more thing, according to the “4111108_ALEOS 4.9.0 software configuration” - Page441,
“AT*SMSM2M_8 sends an 8-bit SMS (requires quotation marks;maximum 140 characters)”
I have tested it and the maximun characters are 114, NOT 140. Plus all the chars, the at command, phone number, quotation marks and CR , there are exactly 256 bytes. Is there some bug in this command?
