I fetched next weeks expected night temperatures from openwethermap.com, put them in a string separated by ‘|’-characters and sent the string (for instance: “|-0.7|+0.4|+2.9|+4.4|+3.5|+1.0|+2.7|”) by blynk-api to my blynk device. All went well, but I was surprised to discover that the ‘+’ characters were not shown in the string. They seem to be replaced by spaces. Does anyone know why and how to prevent this?
