PLS63-W issues to formate the json string | Thales IoT Developer Community

May 20, 2022 - 10:59am, 201 views

HI,
I am sending this ATcmd:
AT^SISD=1,"setParam",hcContent,"{\"current_fw_title\": \"Initial\",\"current_fw_version\": \"v0\"}"
Responce:
+CME ERROR: invalid characters in text string
I have set:
AT^SISS=1,alphabet,"1"
I have also tried '\7B' and '\7D' and '\5F' for '{' '}' '_' , but still the same.

If I remove '{' and '}' and '_' it works.
How do I format these characters so AT^SISD accept the format?
