WISMO 228 characters @ $ ^ _ [ ] { } \ | ` ~ handling

Hello,

I am sending sms in pdu format via the modem.
I can send almost all the characters except the following characters:
@ $ ^ _ [ ] { } \ | ` ~
Can anyone please help me with this problem.
Also, is there a setting needed on the modem?

TIA

Hi TIA,

Thanks for your question, I think we should not classify these message as “garbage message”, but “special character”.

For WISMO 228, which FW version is running?
Try to use latest FW L23a or L22 as this may link to a fixed issue.

Thanks.

Thanks for the reply and will try to load the latest firmware.
