Problems with nrf24l01 + pa lna

rsmls · October 3, 2024, 4:10pm

Does that happen in sync with the sender, or intermittently?

in sync. i have also tried running robin2's code that tests the connection between arduino and nrf, and this is what i've got.

i don't really know what to do anymore, i've tried everything almost. i don't know how to confirm if the modules are fried.

i made them work before, conecting them like this. this was when i didn't have 2 batteries. this worked perfectly save for the intermittent contact of the female wires, but when i pressed them it was fine.

then, i added the gps module.

the arduino and the esp32 arent connected to the stepup, as i'm already powering them with an usb.
when i ran the code like this, one of the wires started melting and smoke started coming out of it. i immediately disconnected the usb and took the battery out of the battery holder. i would think normally think this fried my nrfs or some other component but when i test the voltage everything seems ok, arduino, stepup and stepup are ok.
i have tried the nrfs separated when i bought a new battery and it still worked, though intermittenly, still not sure if it was bc of the poor contact of the female wires.

yet now i don't get anything? not even pressing the wires.

i tried a simpler code.

i tried running robin2's code again after charging the fake battery, my multimeter shows 4.08v. i have running the transmitter on a computer and the receiver on other. this is what my transmitter shows now.

this continues until it reaches 0 again but it isn't consistent. in my receiver end it shows nothing.

Read the link below.

i have tried robin2's code, multiple times as i said before. i tried the old rf24 library that robin specifies in his tutorial, but it doesn't work, it shows an error. when i run the code with the newest rf24 version, at least it compiles the code. external power supply, the same connections, resetting the nrf by disconnecting the power supply, i've read it all. if you want me to read something from the thread specifically please tell me that. also i think the fact that robin didn't update his thread since 2021 is important.

When you mostly see 0x00 or 0xFF in the check connection code, you simply have a wiring issue. It means the MCU and radio are not successfully 'talking'.

This is where you should start looking. Until you get back good data from the radio, there is no point in even trying to transmit or receive data.

It should look something like this:

SPI Speedz	    = 10 Mhz
STATUS		    = 0x0e RX_DR=0 TX_DS=0 MAX_RT=0 RX_P_NO=7 TX_FULL=0
RX_ADDR_P0-1	    = 0x65646f4e31 0x65646f4e32
RX_ADDR_P2-5	    = 0x33 0xce 0x3e 0xe3
TX_ADDR		    = 0x65646f4e31
RX_PW_P0-6	    = 0x04 0x04 0x04 0x04 0x04 0x04
EN_AA		    = 0x3f
EN_RXADDR	    = 0x02
RF_CH		    = 0x4c
RF_SETUP	        = 0x03
CONFIG		    = 0x0f
DYNPD/FEATURE	= 0x00 0x00
Data Rate	    = 1 MBPS
Model		    = nRF24L01+
CRC Length	    = 16 bits
PA Power	        = PA_LOW
ARC		        = 0

From there you, you want to look at adding capacitors, shielding and get your power supply in order. See RF24/COMMON_ISSUES.md at master · nRF24/RF24 · GitHub (scroll down for PA+LNA section)

If you follow the instructions, it will pretty much tell you where your problem is, aside from power supply issues.

is there a reason why my esp32 shows those weird numbers? and why my nano doesn't communicate with my nrfs? i don't think it's fried, i have used it recently to test my gps module.

I'm having trouble following which output is for which device.

I think you are having success with the ESP32, but the nano is just not communicating with the module, so either you have bad wiring there or something else is wrong with the nano/rf24 device.
