RFM69/95 won't run

cYnd

Hi mfalkvidd,

thanks for the welcome :upside_down_face:

You're right, I should use RFM95 and I changed it. However the same error:

208 MCO:BGN:INIT NODE,CP=RLNNA---,FQ=8,REL=255,VER=2.3.2
335 TSM:INIT
350 TSF:WUR:MS=0
378 !TSM:INIT:TSP FAIL
401 TSM:FAIL:CNT=1
421 TSM:FAIL:DIS
440 TSF:TDI:TSL

Also I tried the log parser earlier but it just tells me "Transport device initialization failed". I need to figure out why it can't initialize that device. I quadrouple-checked the wires and can't see any issues :unamused:

However here are some pcitures of it, maybe you find an issue? (Sorry, wiring is a bit messy :alien: )

cYnd

So do you see anything odd in my wiring or do you have any idea why this isn't working?

mfalkvidd

@cYnd my guess would be insuffcient contact, or shorts between two or more pins. Learning to solder well takes some practice. You could use a multimeter to check if there are any shorts. Measuring good connectivity is trickier.

cYnd

@mfalkvidd I tested shorts with my multimeter and didn't find any shorts. However I should receive next week some new of these chips and I will try to solder them new. Let's hope that that's the issue!

Is the SX1278 working with the RFM95 driver as well? All my boards are SX1276 and have a different pinout/PCB formfactor...

niclas

Have you set it up for 434mhz? I think the standard is 866 mhz if not redefined. Also delay is important for certain settings.

I have the same chip working at home, I'll post code tomorrow.

niclas

#define MY_RADIO_RFM95
#define MY_DEBUG_VERBOSE_RFM95
#define MY_RFM95_FREQUENCY (RFM95_434MHZ)
#define MY_RFM95_MODEM_CONFIGRUATION RFM95_BW125CR48SF4096
#define RFM95_RETRY_TIMEOUT_MS (3000ul)
#define MY_TRANSPORT_STATE_TIMEOUT_MS (3000ul)

These are the defines I'm using. All done before including the MySensors.h.

What do you get if you try the above?

niclas

And also:
The fourth line (configuration) needs to be the same on both the node and the gateway in order to work.
Be sure to set the frequncy to 434Mhz on both devices as well.

@niclas said in RFM69/95 won't run:

#define MY_RFM95_FREQUENCY (RFM95_434MHZ)
#define MY_RFM95_MODEM_CONFIGRUATION RFM95_BW125CR48SF4096
#define RFM95_RETRY_TIMEOUT_MS (3000ul)
#define MY_TRANSPORT_STATE_TIMEOUT_MS (3000ul)

Hi Nicals,

thanks for the hints with the defines. Currently I am using this sketch:

#define MY_RADIO_RFM95
#define MY_DEBUG_VERBOSE_RFM95
#define MY_RFM95_FREQUENCY (RFM95_434MHZ)
#define MY_RFM95_MODEM_CONFIGRUATION RFM95_BW125CR48SF4096
#define RFM95_RETRY_TIMEOUT_MS (3000ul)
#define MY_TRANSPORT_STATE_TIMEOUT_MS (3000ul)
#define MY_BAUD_RATE 9600

#include <MySensors.h>
#define CHILD_ID 1

MyMessage msg(CHILD_ID, V_TRIPPED);

void setup() {

}

void presentation()
{
  present(CHILD_ID, S_MOISTURE);
}

void loop() {
  send(msg.set(12));
  sleep(10000);
}

So pretty basic I think. However I still get with your defines the error:

208 RFM95:INIT
292 RFM95:INIT:PIN,CS=10,IQP=2,IQN=0
342 RFM95:PTX:LEVEL=13
364 !RFM95:INIT:SANCHK FAIL
395 RFM95:RSL

Unfortunalety my replacement still didn't arrive (i guess due to the COVID-19 crisis....) so I can just work with the breakouts I got.

What exactly do you mean with:

I can't get is running on one devices (Pro Mini) due to the above mentioned errors, so I didn't even tried it with a second device. What exactly do you mean with fourth line? And which are the "both devices"?

@cYnd Hi! Sorry for really late answer. I must have missed the e-mail notification. Have you solved the issue yet?

I just read your first post and it says: MISO (D11), MOSI (D12). This is swapped according to for instance https://www.circuito.io/blog/arduino-uno-pinout/

MOSI->MOSI and MISO->MISO is correct but the pin number on the pro mini seems wrong?

cYnd

Hey niclas,

no worries :-)

Got still no solution for this issue. On my first post I linked to the shop where i bought it and on the shops spec sheet, I find MOSI on D12. However on the official documentation I also find MOSI on D11. I switched these pins but still get the error:

208 RFM95:INIT
292 RFM95:INIT:PIN,CS=10,IQP=2,IQN=0
342 RFM95:PTX:LEVEL=13
364 !RFM95:INIT:SANCHK FAIL
395 RFM95:RSL

I also found this tool for testing LoRa devices. With MOSI on D12 I just got FF on all addresses but with the switched pins I got:

I don't know if it is a good sign that I see some other values with the test programm or not.
Still any ideas how to get this working?

niclas

@cYnd hmm.. too bad..

I guess I would start by downloading the Lora library by Sandeep Mistry in Arduino IDE and just run the example provided, I think one is called dump_registers. If that doesn't work I would start to suspect hardware failure or some problem with the wires.

And also, check that all the gnd pads of the module are connected to each other. I used a Bluetooth module once that needed all the gnd pins connected.

niclas

@cYnd

Found a picture of my node. I hooked up both the GND pads. Can't remember if it was necessary.

Still no luck with your module?

cYnd

@niclas Still no luck when connection both grounds. Also measured them and they are both connected, even without soldering an cable to it.
I just ordered the RA AI02 modules so let's hope that these will arrive soon and will work (still didn't receive my replacements).

A real pity that I can't get these to work :(

niclas

@cYnd Well I'm out of ideas. Could be a hardware issue, perhaps you shorted something when handling the module or you exposed it to 5V?

Is the VCC output from the Mini 5V or 3.3V? If you supply the mini board with 3.3V you should connect the module VCC to 'raw' if i remember correctly.

I use the RA-01 and RA-02 all the time so hopefully you will be very pleased with them. Good luck!

Avamander

Looking at the images, the wires might not be properly connected, a few wires look like they're just plugged in. In that case even the slightest movement could cause issues.

cYnd

@Avamander The cables are solder from the other side and I just took a picture of the side with the writing so you can trace if it's correctly wired.

Avamander

@cYnd I know, but the lack of proper solder flow (on at least two pins) and a cold joint should not happen even if soldered from the other side. I'd fix it just to be sure it doesn't cause any erratic issues.

cYnd

FINALLY!

My replacement arrived and I soldered it to my pro mini. This time I used a level converter for powering it directly from VCC and not the arduino's VCC. First no luck, but after switching MISO and MOSI it finally worked:

Seems like the diagram of the shop where I bought the arduino is switched. However I can now try to read the sensor and send the data via LoRa! Awesome!

One final question (not related to this issue but maybe you can still answer that in this topic :innocent: ) : I got a RXB6 runnign to read a radio rain sensor at 433MHz. Is this received able to recive also LoRa signals or do I need a dedicated LoRa chip to receive LoRa radio signals?
