Yes With MYSB I always have to do assign a new ID just to get the node to run the first time after flashing. Only true if EEPROM (i.e. ID address location) was cleared. Any chance to get MYSB to know, if a sketch is an flash? And start this sketch, which then will use the defined ID or request a new ID from controller and writes the eeprom? During booting, MYSBootloader calculates the FW CRC in flash and verifies it against the FW CRC stored in EEPROM (which is written after a successful OTA FW update) - if it matches, the sketch starts, if not, the bootloader remains active.

How is the upcoming bootloader release (1.3S) going? I may be wrong but think I need this to push signed firmware to a node. I have a node with soft signing required. The node works but I cannot update it OTA is this 1.3S to support this?
