HI ，SIR
we can not support recored the video to sd for the camera module and sd card conflict in hardware .

HI , Sir
yes , you can use that active antenna .

which icon do you touch in the rakvideo app ?
which micro sd card do you use ?class 10 or less ? we must use the class 10 .

Hi，Why do you think your device is not working properly?Is your device connected to the PC, does the serial port have information to print? The baud rate is 115200. Is your LoRa gateway working properly? What frequency band are you using?

The main chips of the 811 and 811-N are different, so the upgrade method is definitely different. Here is the 811-N information.RAK811-N(Lora).zip

There is no such restriction in the code. What frequency band are you using?

Thank you very much for your question, this is indeed a problem with our documentation and firmware, we will improve this later.

Yes，the RFM95 is a example.

What is your frequency band?

Can you see what number is behind the ERROR returned?

With regard to the last two points you mentioned, can you accept a module with only a single LoRa chip?
