Hi, You have right , but in that case I've the problem of "tight" space , especially at transmitter that must be very small. In second pair, I use PIC16F1847 , no such problems , but there is no space for the same chip for the first pair. I try to use a chip SOIC-8, but with 4 pins that us...

I think that there is something wrong with connections between PIC and NRF24L01. I'll check first the first pair ANALOG TO SPI and SPI TO ANALOG. PIC12F1822 as SPI MASTER CONNECTIONS PIC NRF PIN A.5 MOSI PIN A.4 MISO PIN A.3 SCK PIN A.1 CSN PIN A.0 CE According to PIC12F1822 data sheet , pin A5 can'...

Hi,
Thanks for info..I'll make the changes in hardware about CE pin for transmitter/receiver..Wiki helps me to make the code for both .
It's simple for that pair, but first I must correct hardware.

Regards

Basil

Hi, I was made some tests to first pair (Analog to SPI/ SPI to Analog), In transmitter, I connect an FSR sensor to A1 of PIC12F1822 . I have +3,2V at V+ of NRF24L01 and PIC12G1822. The same at receiver.. I have no data (Analog value of FSR). The current of power supply at NRF24L01 is 0 , instead of ...

Hi,
The small transmitter uses NRF24L01 module to send data to receiver . MCU converts analog value of an FSR sensor to SPI....Receiver gets data and converts to an Analog value .
In the second pair I'll try to use a MAX30100 pulse /oximeter sensor , to make that wireless..

Hi,
I was finished hardware of transmitter and partial of receiver
Maybe tomorrow I'll test the codes for pair transmitter/ receiver for FSR sensor...
I was made a change for PIC in that pair. Instead of PIC 16F18313 I'll use PIC12F1822.

Hi, I was checked connections between 4 pairs according some examples from wiki for NRF24L01... I send you schematics as from them I was made hardware for transmitters and receiver...transmitters for FSR and MAX30100 sensors are mobile , receiver was made in one small PCB that include PIC18F46K22 to...

Continuing some improvements on project I'll try to convert 2 sensors as wireless .. Finally I select NRF24L01 transceiver to make 2 sensors wireless. A. FSR SENSOR 1. FSR sensor with Analog out, is connected to A2 Analog IN on a PIC12F1822 that connected to NRF24L01 module (SPI). That works as tran...

Hello to all! Finally I select NRF24L01 transceiver to make 2 sensors wireless. A. FSR SENSOR 1. FSR sensor with Analog out, is connected to A2 Analog IN on a PIC12F1822 that connected to NRF24L01 module (SPI). That works as transmitter. 2. Another PIC12F1822 is connected to a second NRF24L01 module...

Hi Stefan,
I know that pin 5 of HC-12 module must be set to GND...I used another Serial Terminal, and setup works OK..
Now I'll try to use a pair of the module to make sensors wireless..
Thanks
