Hi Is there any way of changing the SSID of the Photons soft AP? We are doing a demo and would very much like it to show our product name instead of Photon-XXX //Henrik

Not sure what to suggest. I just tried it here with a 12-character SSID and it worked. Double check the contents of the ssid_prefix file that’s produced with a hex editor (or use xxd to dump to binary) to be sure nothing spooky has crept in there. Mine is a 13 byte file that looks like this: 00000…

Yes! Ok, it seems the problem was integers < 10 in hex representation need to be specified using a leading 0 when saved to the SSID prefix file. So, for example, "\x7Example" was getting saved as 7e78 616d ... instead of 0745 7861 .... The fix was saving the file as "\x07Example".

Which OS are you using? For me the single char was working on OSX…but so does 0 padded, so let’s stick to that. I’ll edit the original post.

The problem was probably that the ‘E’ in ‘Example’ is a valid hex digit. Whereas the ‘M’ in ‘Matthew-MDMA’ is not. So, \x7Example was getting interpreted as \x7E + xample, but since ‘M’ isn’t a hex digit (and likewise for ‘R’ in the ‘Rad’ example), the shell was stopping with the last valid hex cha…

You’re absolutely right! It did bother me that \x3Rad had worked (which was all I had to go on initially) but not others. I guess it really just means you definitely got pad those 0’s to make sure the integers get parsed correctly.

I have following the instructions: I have installed the DFU driver (windows x64) The prompt, etc. When I write: #echo -e -n "\x03Rad" > ssid_prefix (It's OK) When I try to upload in the dfu: #dfu-util -d 2b04:d006 -a 1 -s 1826 -D ssid_prefix I receive the following: Copyright 2005-2008 Westo…

I have just achieved in a Ubuntu 14.04 machine without problems :smiley: It would be great if you could complete @mdma instructions for Windows User. Thanks

@mdma could you share the ETA when it will be available via code? We are planning to ship a 1000 particle based products to our customers and it’s going to be painful for us to rename each of them via DFU mode. I have the same scenario as @henkep

I just did this today with the code below. System.set(SYSTEM_CONFIG_SOFTAP_PREFIX, "Gizmo"); Edit: removed the code to check the value was already set since @mdma mentioned that System.set does it by itself.

The suffix is generated using the RNG build into the device.
