DA14531 firmware update without using motherboard

I would like to program the Codeless AT firmware into a DA14531 Tiny module. I have the hex file, and I have SmartSnippetsStudio2.0.14 installed on my Linux machine. However, SmartSnippets can't seem to connect to the module. I see serial port activity on the scope, so I think the serial port is correct. I am using 1 wire to J14 (P0_5). My hardware setup is:

Linux host -> FTDI interface -> 2-wire to 1-wire circuit -> DA14531 Tiny module

我不是主板目前使用对话框to do this -- is it possible to program a Tiny module directly as I am trying to do?

Does anyone sell the Tiny module with the Codeless AT firmware already programmed?

Thanks,

-Chris
