I have a pair working at low power. I have the version with a power amplifier and LNA on the board. I need to know how to enable the Power Amplifier to high power and the LNA to maximum gain. I know it is operating without the power amp because of the current draw, and nothing I can do seems to turn on the power amp. I have 3 operating units so I am fairly sure it is not a hardware failure. If anyone has one running at high power please post me a code snippet. Larry
It would help if you told us what you've tried. For example, did you try the setPALLevel(), and if so, what value(s) and data type did you pass to it?
I cannot find any code or examples of what or how to pass anything other than PA out power like: radio.setPALevel(RF24_PA_HIGH); so if you have any experience or an addres that has some setup code in it I would like to see some. I am using the library from maniacbug. It appears all published code I can find is written for boards without the preamp and poweramp. I can tell by the current draw that the power amp is not running. Larry
What are you comparing the power output to? I see no information anywhere i've looked, that tells me anything more about the module with the PA and LNA than the standard module. That leaves me wondering if the PA is running all the time, and only amplifies whatever is handed to it.
Do you have any standard models, and did you check the current draw on them?
Did you get a current difference with the various power level changes (with setPALevel()), with either standard or amplified modules??
Hmmm... there's one user on here named GROB, who has set up a network using both the low power and amplified modules. He participated in a thread this year, and here's one of his posts from it: Help choosing the right wireless module - #2 by gr0b - Home Automation - Arduino Forum
You might want to ask him about it (or perhaps ask maniacbug).

I have only used the non-amplified variants so I don't know whether/how the amplifiers can be configured. If the standard RF24 config options don't control it then I suggest looking for information from the manufacturer or supplier of your board.
Thanks for the input, I will try contacting one of the two above. If anyone has one of these running at high power (+12DBM) let me know how you did it and the code you used. Larry
