BluetoothLE string management

Good news, now it's OK ! I don't really know why, but I had to declare the characteristics as "BLERead | BLEWrite" and to use a sequence : WriteStringsWithResponse + ReadStrings instead of WriteStrings. Here is my new block sequence : [Capture3] Notice another error that I fund : The WriteByteWithResponse of "13" value +ReadBytes sequences shall be done at the end, after having broadcasted the Strings (if not, the "updateBio()" subprogram is launched before update of strings). Hope it will…
