Hello, I have a problem NRF905. Sending distance is 0-30 cm maximum. I want to ask if the defective product or it may be due code? TX RX uses the base code of the library.

Hi, Can you share the schematic of the module, and the voltage on all the wires? I have a feeling there is some poor grounding here.

Hello, this is connect

Connect Arduino UNO

VCC = 3,3V CE = DIGITAL PIN 4 CLK = unconnected, I did not know where AM = DIGITAL PIN 9 MISO = DIGITAL PIN 12 SCK = DIGITAL PIN 13 GND = GND

TXE = DIGITAL PIN 5 PWR = DIGITAL PIN 3 CD = DIGITAL PIN 7 DR = DIGITAL PIN 8 MOSI = DIGITAL PIN 11 CSN = DIGITAL PIN 10 GND = GND

both Arduino UNO involved as well.

Library uses this

I used a basic version code. Nothing I have not changed. Within one Arduina recorded RX and TX to another arduino. Im used example code.
