Hi,
There is a CTRL-B that emboldens any selected text.
No problems, except only the first image has displayed.
How are you powering the project?
I see you are using Vin and gnd, I hope you have 7V or more if you are using those pins.
Vin needs to be at least 7V to enable the on board linear 5V regulator to function correctly.
Do you have a DMM to measure your 5V pin with respect to ground.
It looks like you are using a NRF interface board with a regulator on it, so you can use 5V to power it.
You might want to try the other images, but make sure they are not many MB in size.
I find keeping and image about 1200 pixels on its longest side produces the easiest image to upload.
You are now in troubleshooting mode and need to test each part separately.
There are even test codes to check if your NRFs are talking to each other.
Have you had the NRFs communicating at all?
Tom..
