RE: Interfacing nrf24l01 and SPresense
@satish Library which you are using for NRF module is NRF24 which interfaces over SPI protocol, if you want to use NRF module with spresense you can implement your own code using standard spresense arduino library which contains SPI interface library and examples
In my personal opinion, I have tried nRF24L01 earlier they demand very specific voltage and prone to signal disturbance, you can use ESP8266/32 for similar application which is easy to setup [serial communication with spresense] and use ESP-NOW protocol which offers same functionality as NRF and in more secure, fast and easy way.
RE: how to rectify attribute error?
@lakshana This error arises due to pyreadline incompatibility with Python 3.9+.
There is a temporary fix by replacing
xmodem.pyfile in line 532, 537 and 551.
This fix is mentioned in pyreadline GitHub issues.
I have opened a PR in edgeimpulse firmware repo here for future fixes.
RE: Accessing image buffer for preview image
@itcandowhat Hey, I have tried several methods and yes you will face low FPS problem.
In your code you are implementing buffer solution, one possible problem can be data getting corrupt before writing new data or similar problem.
You can try sending data over serial first as mentioned in this post
There is serial live feed available in edge impulse also but again low FPS problem
Best thing you can try sending images over serial and stich in real-time but sony spresense is IoT-development board and more powerful solutions are out there for real time video recording like raspberry pi high resolution or OpenCV OAK series which are available in USB and POE connections
