I looking with a magnifying glass at the chip, i noted that this is NOT NRF24L01+ but just a NRF24L01 without the plus.
I used this smaller versions and they worked immediately. I_GATEWAY_READY message appeared. http://www.ebay.com/itm/2-4G-NRF24L01-PA-LNA-Wireless-Module-with-Ceramic-Antenna-1-27mm-/400746941364?pt=LH_DefaultDomain_0&hash=item5d4e610bb4
MySensors did post a warning on that: http://forum.mysensors.org/topic/728/radio-setup-give-check-wires/16
The node is a very simple one. So I never considered boot loaders, as the node would not need changing sketches during it's lifetime. I have boot loading functionality on my other designs, this one is a minimal board. Any extra chip would beat the purpose of the word "minimal".
It's a dumb node for a reason
Hi @berkseo. Thanks for the suggestion, but could you describe in more detail? As for my TODO list, there is already a task to add 485 interface to the gateway. My latest device "xRoom" have this interface.
ps/ Where have you gone?
I have been working on "xRoom" shield. A small announce:
Do you remember the discussion about multinode? So, it will be available soon))
Thanks @hek and @kalle
Sorry, but I'm not good to understand the debug of the scanners.
In the RF24/examples/scanner/ the range is between 0000->->->7777
Those are the high order nibble of the channel byte. The low order nibble is just below it.
The 125 channel numbers are printed "sideways" in hex.
I would expect a list of channels between 1 and 13.
You're thinking of wi-fi. This isn't wi-fi.
In the second scanner (wiFi scanner found on arduino forum) It's more accurate. It seems noisy between channel 3 and 9.
So, the questions are:
What does default channel 76 mean? 2476Mhz?
Would mean above channel 13, on channel 14. In this case these channels are free, based on the results. I've seen I can use:
#define RF24_CHANNEL 76 //RF channel for the sensor net, 0-127
How to interpret the scanners result? Most of all the "RF24/examples/scanner/" which has an output I cannot identify in a channel.
The bigger the number below the channel, the more active it is.
I would like to understand the result and so choose the right channel, not only trying without knowing what I'm doing
Thanks a lot for the support!
