Description

@sdetweilsdetweilopened on Aug 16, 2021

I have a characteristic created with a string value. and now I need to change it...

but writeValue() doesn't work

BLECharacteristic hashCharacteristic("9AFF", BLERead," 12345"); hashCharacteristic.writeValue(encoded,sizeof(encoded),false); // overlay default with actual, doesn't work hashCharacteristic.setEventHandler(BLERead, hashCharacteristicRead); ledService.addCharacteristic(hashCharacteristic);

whatever I set it to at create time, that is it

and I can't remove a characteristic..

if I stop Advertising, can I add the same characteristic and overlay the old one? or do I have to recreate the service?
