Hi, OK so I am quite happy compiling code using the Dev environment. Then I can flash into my USB-connected Photon - all goes very well. BUT - it seems that there is then no way to send that same binary image to another Photon - withut plugging it into my USB ???. Seems I have to re-compile it every time 😮 So - OK its probably me - and I must be missing something…but I ‘think’ I have looked everywhere I can think of ???. The problem is of course compounded if I have a version of code built with a previous firmware release (like 0.4.6 for example) as the Web IDE is the only (as yet) environment where I can define the firmware to build against ??. What (I think) we really need is to be able to tell CLI particle flash xxxxx mycode.bin but it doesn’t work ☹ Don’t get me wrong - I think the Photon is a wondrous beast, and want to deploy more of them…LOTS more 😉 Thing is that I have a colleague who is testing the ‘product’ before making it live - so I need to send him a binary and say put this into all your test boards…currently he needs to plug each one into a USB 😮 Many Thanks BR Graham ---

If you don’t want to flash via DFU-Util, you can do it over the air. Please read the doc here: [https://docs.particle.io/reference/api/#flash-a-device-with-a-pre-compiled-binary](https://docs.particle.io/reference/api/#flash-a-device-with-a-pre-compiled-binary) ---

Hi, Yup I just managed to do it :-O. The first few times I tried it didn’t seem to work :-O. Sorry I seem to have been talking out of my \*\*\*\* 😮 Mind you I also just had a 'mare getting some variables registered on the same module. Kept loading the code and it just didn’t seem to do it - nor did it report a failure…theres a Gremlin in my code somewhere… Sorry to have bothered you again - I did try quite a few times though - honest guv’… Mind you - your doc tells me a different way :-O. Are you sure you didn’t just change this feature :-O. I swear that an hour or two back the following did not work !! - hence my post… CLI particle flash xxxx mycode.bin Now it works like a charm ;-)). If you didn’t change it - I’m going mad - if you did GREAT - MANY THANKS 😉 Pity the evidence scrolled off my CMD window … BR Graham ---

Has been there as long I know CLI 😉 ---

Hi, So sorry - I tried this quite a few times some time back and gave up - then again this afternoon and it still didn’t seem to work. Looks like I have 8 major problems then - 4 on each hand ☹ Thanks once again… BR Graham
