At+wipfile=6,1,2 return 'Memory allocation error' (+cme:836)

Hi, while trying to use at+wipfile=6,1,2 to send email, I encountered a case of ‘Memory allocation error’. +cme error: 836 and causes a modem reset.

I was able to send other messages, so it would appear that certain characters in the message triggered a reset.

Any thoughts of what would might have caused it? Thanks.

Which version of Wipsoft are you using?
