How to bring up the network in Spresense?
-
Dear all,
I am working on a project which requires to capture images and store for neural network training purposes. I am using the camera example to do it. But the limitation I have at the moment is that I cannot go on capturing images for long time, e.g. leave the Spresense for couple of days to capture huge number of image samples because of the SD card cannot accommodate that huge number of files. Hence, I am thinking of writing an external script which runs remotely to the Spresense, and connects to the Spresense time to time, log into it (ssh), copies the images off to a network drive and hence make space in the SD card. To start with I need to bring up the network in the Spresense, assign an IP (or maybe it gets an IP from the DHCP??) and then try log in into the Spresense remotely to see if that works. Has anyone tried this already? Please share your thoughts and point me to any documentation(s) if available.
Thanks and regadrs,
Vivek -
I just noticed that there is no network driver in the Spresense tree (master branch) right now. I did the below:
$ make menuconfig
and the below screen comes up which has no Network driver option:
image url)So the question is how to integrate the network support in Spresense. Please point out if I am missing something here.
-
Ok I just realized there no Ethernet on the board. Hence, installing net driver is not an option. Is there any known wifi extension board which works with Spresense? If yes, please point me towards that. Thanks again.

Hello @vivekbhadra Sorry for getting in the middle, I am working with Cameras and AI too (for inferencing and to store a few selected ones). Your post caught my attention. Sending the images over WiFi is a good option and it will give you some freedom, BLE to another device for cleaning purposes could be good too, you have several cores, one of them could manage the cleaning process behind the scenes (Just guessing, I don't know what you are doing). Now, if you don't need the images all the time, you could replace the old ones by the new ones.
Cheers and good luck with your project.

Hi @vivekbhadra
I think that the best way would to have Spresense send pictures over Wifi to free up the SD card.
To get the wifi to work:
https://developer.sony.com/develop/spresense/tutorials-sample-projects/spresense-tutorials/how-to-equip-spresense-with-wifi-connectivityI have a set of drivers for ESP8266 that have been ported to Spresense SDK. I will have to email them to you since I can't upload them here.

@TE-KarlKomierowski Thanks a lot Karl for sending the ESP8266 drivers. I will try integrating it in the Spresense SDK. Just to double check, has it already been integrated in the Spresense SDK? In that case I would not spend time on integrating it. But if not, do you have the Kconfig file for the drivers? Thanks again.

Hi, no they have not been integrated. I simply add them to my makefile to compile to object files to be linked together.

@TE-KarlKomierowski ok thanks. I tried compiling the drivers source file and I am getting the below errors:

In case you still have the same header file, would you mind pass it to me please?
Cheers

Hi,
The wifi.h file was just a plain header file holding my wifi credentials.
Just remove it, or create it, and add the missing defines you will get when you build next time.

@TE-KarlKomierowski I have now integrated it into the SPRESENSE SDK. I have attached the patch for the changes I had to make for integrating it into the sdk. Also, I have taken out the source code from the patch file.

@TE-KarlKomierowski I would also like to receive the ESP8266 driver by mail, thanks.

You should have them now, I just sent you an email.
Please let me know if it didn't work.

@TE-KarlKomierowski Thanks but im looking for a bit more then the arduino ide...lol. Can you please get me a copy of the ESP8266 driver you mentioned. Thanks
-
@TE-KarlKomierowski please send me an email with a copy of the drivers for the esp model as you have done for the others in this post. Thank you.
