Couple of questions on this module.
My module backlight seems quite dim. The screen is only really visible in low light. Certainly a lot dimmer than cell phone screens I have.
I have the backlight connected to +5v.
Secondly, how many bits per pixel colour does this module support?

Re: nRF24L01 2.4GHz Wireless Transceiver Module (HCMODU0004)
Well can't really say why, but adding a 2ms delay between setting the address of the receiver and setting the payload fixed it! /* Set the receiving address of this module. This must be a 5 byte * character string */ Mirf.setRADDR((byte *)"SENS1"); //without this transmissions fail with status 46 wh...

Re: nRF24L01 2.4GHz Wireless Transceiver Module (HCMODU0004)
Yes, the transmiter is going through sleep-wake cycles with power on all the time and the receiver works fine from power up. If I power off the receiver and then back on, no packets received until I physically power cycle the transmitter. I assume the protocol between the radios means both ends need...

Re: nRF24L01 2.4GHz Wireless Transceiver Module (HCMODU0004)
Actually I have found that the link is not dropping over time, it's the receiver being switched off at night! For some reason, if the receiver is turned off and then back on, it does not synchronise with the transmitter (which has remained on). I will do some digging in the datasheet to see how the ...

Re: nRF24L01 2.4GHz Wireless Transceiver Module (HCMODU0004)
A further question for you. I have been testing a pair of radio modules for a while and found that I get lost comms after a while, probably something like 12-18 hours. In my set up I have an arduino pro mini with a pir attached. I put the processor and radio into power down mode and wake on interrup...

Re: nRF24L01 2.4GHz Wireless Transceiver Module (HCMODU0004)
Got it going now, I put the 10uf caps on BOTH boards! (previously only on the tx board!) Range is pretty good, works over most of the house (big house with lots of brick walls). Antenna direction becomes sensitive at extreme edges of range as expected. I'll get some more as I want to do some home au...

Re: nRF24L01 2.4GHz Wireless Transceiver Module (HCMODU0004)
I meant that I copied the code example from here and added some register reads, that's all. I made some progress by monitoring Carrier Detect and the receiver is certainly seeing the Client transmissions. It will detect carrier on the same channel and a couple of channels either side too. I'm not su...

Re: nRF24L01 2.4GHz Wireless Transceiver Module (HCMODU0004)
I've copied an pasted the demo here and used the same library: Mirf library by Nathan Isburgh. The mirf.cpp file was last updated 11/3/2011 I'm not sure if there is some issue with the Plus version of the chip, as the library mentions nRF24L01+. It is odd that I was getting some packets across but n...

Re: nRF24L01 2.4GHz Wireless Transceiver Module (HCMODU0004)
I have tried reading out some of the registers:
Both read as:
RF setup : 00001111
Config: 00001011
Rf channel:90 (tried 6 and 50)
Status: 00001110
fio status:1
The client shows Lost tx packets incrementing to 15 and the retransmitted counter stays on 3.

Re: nRF24L01 2.4GHz Wireless Transceiver Module (HCMODU0004)
At the moment I'm not getting any received packets.
I did try reducing the data rate to 1mb but that made things worse and since trying that, no received data at all.
I have tried swapping boards over but no difference.
