Range-testing my nFR24L01: Logging

Projects Programming
1

Hi guys,

For a project I want to let two Arduino's communicate to eachother on +-500meter.
Yesterday I created an setup with a Arduino Uno and Nano with 2 nRF24L01's.
The first range-test resulted in an amazing 335 meter!

Now: I want to change the nRF24L01's to the nRF24L01 (with external antenna). I want to test te range of these antennas by putting one Arduino Nano underneath my drone and fly away to see if there is still a connection on 500m.

Is it possible to add a piece of code so that, if I send a signal from the transmitter it logs the time?
And of course the same on the receveier: if it receives a signal it logs te time too?

If so, I can use my drone-log to check out what the distance was when I lost the connection.

Feel free to share your thoughts if you have some better ideas!

Thanks in advance

If the number of data points to be logged is not large then the data could be saved to EEPROM and read back later. Alternatively the data could be saved to an SD card but that would require extra hardware.

If there is no issue in using extra hardware then a GPS receiver on the drone would allow you to record the absolute position of the drone and/or to send it back to the RC transmitter.

I don't have a feeling yet about how many data points could be saved on the EEPROM, but it's worth a try before buying an SD-card module.

I already have an DJI Inspire with GPS. The thing is that I want to add an Arduino to it and send a signal from the transmitter to receiver. But how am I able to check if the receiver is receiving the signal that I'm sending at around 500m?

Put the transmitter on the quad then do the data saving/analysis on the ground.

How will you know how far away the quad is at any time ?

You bought an Inspire and are now reluctant to buy an SD card. That does not make sense to me.
