problem using nrf24 and mpu6050 with dmp enabled
hi!

i have a nrf24 and a nrf24 with an antenna but they dont catch each other. the code i have is for my drone but i have taken out the code for just the radio so its easier to see whats happening. here it is:

reciver:

#include <nrf24l01.h>

#include <printf.h>

#include <rf24.h>

#include <rf24\_con…
you write an int, but try to receive a c-string, that can not work.

the radio will not be available (i.e. have a packet received) 99.9% of the time,

introducing a delay and printing something if that is the case is just crazy.

so your code seems to be copy and pasted crap without any understandin…
Your card is ok. There is interference between the router and your computer.  

  

1. The router or the PC may be "hidden" behind a metal cabinet, refrigerator, etc.  

2. Move router higher  

3. Microwave ovens and some cordless phones (not cellphones) that use 2.4GHz will interfere with the 2.4GHz WiFi signal.  

4. Point the router antennas in-line with the direction of the PC.  

5. Move the router closer to the PC. wow.

good idea with the packages. i have compared it with another system. the package “opennms-plugin-protocol-radius” is missing here. (we use radius login)

i installed it and opennms works now.

but in the meantime i have deactivated 5 adapters. i’ll take that back one by one. let’s see what hap… Solution

![image](https://q2a.s3.us-west-1.amazonaws.com/prod/answer-four-long-current-carrying-wires-planeintersect-form-square-side-lengths-1.gif) did you get a replacement receiver? need to activate it? check our article above to learn how.

i am pretty sure you are going to need a pc with a parallel port, once upon a time there was a usb adapter available that worked for this radio, the driver is available but you will most likely not find the adapter.
i had to run windows 7 32 bit to get mine to work.
i used the version of powersdr from the ke9ns website called excalibur, if you can't find it i have it backed up on my nas. hi,

i can compile your code without error.

could you help to double check your makefile and environment?

environment is set by jetpack2.3.1

i looked into the av, which was moved to a different server and upgraded shortly before our windows 7 project began. evidently, trend's migration tool that was used did not migrate over port exceptions in the firewall. after adding a few recommended exceptions to the firewall, everything started to work. 
it seems that the client firewall was blocking return snmp traffic from the printer which was keeping the computer from realizing that printing had completed. this was keeping the connection open to the printer preventing anything else from printing on that computer or any others connected to it. 
the ports added as exceptions were: udp 161(probably the only one needed), tcp 9100, 9220, 9500. Hi Jamey6588540,Please follow the steps mentioned in the below link to fix the paper capture service:[Could not access the recognition service when attempting OCR on Windows](https://community.adobe.com/external-link.jspa?url=https%3A%2F%2Fhelpx.adobe.com%2Facrobat%2Fkb%2Facrobat-could-access-recognition-service.html)Divya If you install fiber optic link between to points, it can not be wiretapping without notice. But with satellite is giving some options for that. Maybe you should hide your data by encryption systems between two points.  

good luck!
