hi everybody, so i’d like to parse a BLE string sent from an esp32 that has this form (^9^^FIZZ23010,-39^^H). the ‘^’ is the delimiter. the problem i have is that everytime there 2x ‘^’ back to back it create an empty item in my list. I’d like to have a list with no empty strings. I tried whats in the image but had no sucess so far.

thank you guys

Hi @ocorbo, can you try adding a space in `does j contain empty string` block and seeing if that helps?
