NRF24 Init fail with Arduino mini pro 3v3
I've a sketch which is working fine with arduino Uno, the exactly same sketch in arduino mini pro is failed :
0 MCO:BGN:INIT NODE,CP=RNNNA--,VER=2.1.1
6 RF24:write register, reg=0, value=14
14 RF24:write register, reg=3, value=3
18 RF24:write register, reg=4, value=95
22 RF24:write register, reg=5, value=76
26 RF24:write register, reg=6, value=39
30 RF24:write register, reg=16, value=115
36 RF24:write register, reg=29, value=6
40 RF24:read register, reg=6, value=0
45 RF24:read register, reg=5, value=0
47 !RF24:INIT:SANCHK FAIL
51 !TSM:INIT:TSP FAIL
57 RF24:write register, reg=0, value=12
The NRF24L01 is working fine (it is a same that is running in Arduino Uno), My arduino mini pro seems to working fine (I've tested with Blink sketch).
For connection I've followed :https://www.mysensors.org/build/connect_radio#nrf24l01+-&-arduino
To power supply my arduino mini pro I've used 3.3V pin from my arduino Uno, I've also connected VCC of NRF24L01 to 3.3V
Do you have an idea of what is wrong ?
Thanks for your help.
Why aren't you just supplying 5/6v to raw pin of the pro mini?
Ok thanks gohan
So you suggest that i apply 5v from my arduino uno in raw pin of mini pro, right?
And how power supply nrf24l01?
Don't you have any 5v supply around besides the UNO? For 3.3v you can get those from the pro mini. Also check cables, most common problems are bad wiring or loose connection.
Today my setup in on breadboard and I did not soldered pin of my arduino and my issue comes from bad contact on pin between arduino and NRF24.
