I have one the "SMA-CONN" with label from Banggood, https://www.banggood.com/Ubertooth-One-Bluetooth-Protocol-Analyzer-for-Bluetooth-Sniffer-Experimentation-Build-in-LPC175x-ARM-Cortex-M3-Controller-RP-SMA-Connector-Premium-PCB-2_4-GHz-Transmit-Receive-p-2026714.html, which has the same problem. It reports Firmware version: 2018-12-R1 (API:1.06) but will not go into DFU mode to upgrade...
With the "SMA-CONN" version is it likely this a software only issue with maybe the LPC175X not having been programmed with the correct/full firmware or some flash access registers set...
There is disagreement between the KiCAD schematic in this repo at https://github.com/greatscottgadgets/ubertooth/tree/master/hardware/ubertooth-one and the documentation at https://ubertooth.readthedocs.io/en/latest/firmware.html around the 6 pin header. Looking at the actual board I suspect repo...
Ok from the processor data sheet it does indeed look like you can flash the processor to stop future updates. If the factory wanted to protect 'their' IP they could...
Ok I have resolved the disagreement between the KiCAD schematic in this repo and readthedocs and both are correct. This the schematic if you want to save time opening KiCAD...
Good news, using a probe jig and a USB to serial adaptor I was able to access the bootloader ROM and flash new code so mine is now running API...
Just close out things from my experience here is the response I got from Banggood that appears to backup up what I found: _Please check the solution below, if there...
 @zatarra Attached is a picture of the rear of the board where I have marked up the connector where I was using a pin jig. I used the SMA...
@zatarra One thing that did catch me out is you can program the app firmware and it appears to work until reset. What I had to do was program the...
@zatarra Based on the DFU process working over USB I would say it is likely that the Ubertooth is now correctly working and it is the PC end that needs...
