Thank you all for your thoughts.

@ kolban, It is true that Bluetooth speed 2.1Mbps, but on couple of forums, I read that 1.5 to 2.0Mbps is good enough for 720p @ 30fps. Perhaps frame rate can be reduced to 24. @ WiFive, Since the smart phone will be in very close proximity, and Bluetooth consumes less power than Wi-Fi, I just got t...

Thanks for reply. There will be a H.264 encoder at the source. So basically, this is what I'm thinking, but I'm not sure if it will work.

{Camera --> ISP + H.264 encoder --> ESP32 (Wi-Fi)} --> {ESP32 (Wi-Fi) --> ESP32 (Bluetooth)} --> {Smart phone (Bluetooth)}

Hello,

Just joined the forum. It seems that ESP32 is a very nice radio. I would like to know if ESP32 can be used to downstream 720p@30fps video via Wi-Fi and upstream same video via Bluetooth. A few millisecond of delay is OK between down and up-stream. Thanks in advance.
