Bad range

[n3ro]

is it possible that my wifi router make problems with mysensors?

This must be a problem with your nrf modules. 3m is nothing. The cheap version you are u sing should have a range of about 10-15 meters in normal buildings. The better version LNA+PA works for ranges >20 meters with multiple walls in between.

@n3ro It is possible - try changing 'channel' in RF24 Config on every node (by reflashing it).

[n3ro]

@andriej this sounds interesting. what is to do to reflash it?

[andriej]

@n3ro just change the channel in config file (try to set it in higher values in example) and reprogram all sensors and gateway on your network.

[n3ro]

ah okay. So far I have this sketch to test the distance:

tomorrow I'll reflash all nodes+gw and test it again :)

i have still a band range. next i will test a gw with a nrf antenna version. i hope this helps

If you're using the cheaper low-power variants of the nrf24l01+ on the gateway then make sure that your MyConfig.h file has RF24_PA_MAX for RF24_PA_LEVEL_GW.

I noticed the other day that the default value from GitHub is RF24_PA_LOW, which gave me only a couple of feet of comms. Changing the default made everything work much better. Seems like the default repos is set up for the high-power radio variants.

@rickmontana83 YEAH!!!!! This has fixed my problem!!

Now i have much better rage with my nodes :+1:

Big THX!
