    Is there a way to "unbrick" a CYBLE-212023-10?


      I have a CYBLE-212023-10 module soldered to a board.


      I tried to use the CySmart Android app to upgrade the firmware to the latest version using the "CYBLE-2120XX-X0 EZ-Serial FW Image V1.1.1 (.hex, app.cyacd, stack.cyacd)" download, but now the module is completely unresponsive. I think I must have messed up the upgrade somehow.


      Is there a hardware-level way to force it into the OTA bootloader so I can try again? Eg a pin I can pull low during power-on, or something like that?


      I'd prefer not to have to remove it. I'm not sure the main PCB will survive.
