[Youtube] WBR2/WBR3 - RTL8720CF flashing step by step guide/tutorial - how to solder and flash
RTL8720CF/W701-VA2-CG can be easily flashed just like ESP modules - you just need to connect few more wires. Here's a step by step video showing firmware change process for WBR3 and WBR2 modules, which are using mentioned Realtek chip. This way you can free your devices from the cloud and pair them with Home Assistant.
This guide is applicable to the following modules with the core chip of RTL8720CF or similar, so: WBR1, WBR2, WBR3, WBR2L, WBR3L, WBRU etc.
See full guide:
After finishing the guide, you can do the configuration futher like on our other videos on the playlist:

a user on this forum kindly sent me some WBR3 modules for testing. The location of those pads on the rear is a pain, as already stated. I think I will turn the CR3L Bluetooth Gateway chassis into a... [Read more]
Will you route out the pad on the module back? I did it, just to be on the safe side - it may be needed if I brick the OTA. https://obrazki.elektroda.pl/6443591600_1738841842_thumb.jpg https://obrazki.elektroda.pl/4473560000_1738841840_thumb.jpg... [Read more]
yes. initial idea is that all should be routed to the outside case for every eventuality [Read more]
So you have two options: 1. do just like me, route out a wire 2. is this just a twosided board and copper ground pour is on both sides onder WBR3 place? If so, maybe you could... well, carefully cut... [Read more]
likely this, but maybe with thin enamelled wire hadn't thought of this, but it looks like most of both sides are covered by a ground plane so that would need careful avoidance/isolation from the... [Read more]
The PCB edges would be needed to be sanded with sand paper. Btw, I still have those 3 from the reader: https://obrazki.elektroda.pl/6737341400_1738845723_thumb.jpg I will probably swap them... [Read more]

Very nice idea. Remember to add more grounds and VDD pins in advance. Also, we really need to check if it 's possible to print pin names on paper, it would help a lot if we could label this connec... [Read more]
oh. I thought 3 GND and 2 3V3 would do for now. Plenty of space if more needed though Added after 45 : which connector? [Read more]
This one obviously: https://obrazki.elektroda.pl/2609557500_1739031818_thumb.jpg I need to do the same for my dev board: https://www.elektroda.com/rtvforum/topic4062695.html [Read more]
I have labelled it! https://obrazki.elektroda.pl/9486103600_1739032163_thumb.jpg https://obrazki.elektroda.pl/8153794200_1739032190_thumb.jpg [Read more]
Ah right, sorry, I didn't see. It seems that we need to use "big thumb" image option more often. [Read more]
