@luizrrocha Can you post your sketch and (if available) debug log here?

@electrik Probably this is PubSubClient-related. Please provide additional infos:

• ESP board definitions version
• MySensors version
• GW sketch

@eiten A similar approach was used for a NRF5 +PA/LNA module: https://github.com/mysensors/MySensors/pull/1414/files#diff-7b958e4728831b83d2359a08827bcae1R64-R80

@eiten Would be helpful to see the debug logs (in rfm/sx verbose mode)

@eiten Yep, already saw this one. Based on the heltec implementation, the sx-registers are mapped to specific memory regions of the mcu. Would be interesting to have here a complete ASR-specific documentation...

@eiten Great job! Did you come across an "usable" ASR6501 datasheet - so far the information on this SoC is rather sparse?

@Avamander Can you upload both, the GW and node sketches from the working pair nanoGW/megaNode? Also, it would be helpful to see the full GW log from the non-working combination (nanoNode/megaGW) with MY_DEBUG_VERBOSE_RF24 enabled. If time allows, I'd like to reproduce and test your setup.

@FullMetal said in Node to Node Communication via Gatreway: Please upload the debug logs for further troubleshooting.

@Joerideman Glad to hear you finally got FOTA working - generally speaking, you can do both, serial FW uploads and FOTA, however, switching from FOTA to serial updates or vice-versa, you may want to clear the FW checksum stored in the EEPROM as instructed above. If your sketches are rather large or for prototyping/dev, I'd advise you to use the optiboot bootloader as the serial uploads are faster and the optiboot bootloaders uses less flash storage...

@Joerideman That looks already much better!

For the sake of completeness, here is the modified MYSBootloader source code.

Try clearing the EEPROM and then re-assign the FW

@Joerideman You can ignore that warning (it is related to rm not being found).

Can you try this .hex file: CE=8, CSN=9, CLK=8MHz, BAUD=57600, RF24 channel=122: download file

Please post the log of the bootloader flashing process...

@Joerideman Thanks, I again had a quick look at your HW.h file and found the issue:

// set pin mode: MOSI,SCLK,CE,CSN = OUTPUT, MISO = INPUT (=> all on same port)
SPI_DDR = _BV(SPI_MOSI) | _BV(SPI_SCLK) | _BV(CE_PIN) | _BV(PB2) | ~_BV(SPI_MISO);
CSN_DDR = _BV(CSN_PIN);

SPI_DDR and CSN_DDR are both pointing at DDRB:

// SPI communication
#define SPI_PORT	PORTB	// 
#define SPI_DDR		DDRB	//

and

#elif defined(SPI_PINS_CE8_CSN9)
	#define CSN_PORT	PORTB	// port for CSN
	#define CSN_DDR		DDRB	// DDR for CSN
	#define	CSN_PIN		PB1		// Arduino Pin 9 <-> Bit 1 of port B

Thus, setting CSN_DDR = _BV(CSN_PIN) you overwrite SPI_DDR. Comment out the second line and add _BV(CSN_PIN) to SPI_DDR:

// set pin mode: MOSI,SCLK,CE,CSN = OUTPUT, MISO = INPUT (=> all on same port)
SPI_DDR = _BV(SPI_MOSI) | _BV(SPI_SCLK) | _BV(CE_PIN) | _BV(PB2) |  _BV(CSN_PIN);
//CSN_DDR = _BV(CSN_PIN);

@FullMetal Please post a full debug log of both nodes showing the observed behaviour.

@Joerideman Yeah, I assume something is wrong with the bootloader configuration. Can you zip and upload all bootloader files (or the entire folder) you are using with all the settings and modifications you did?

@Joerideman The bootloader doesn't generate serial debug output, would be helpful to see the GW debug log

@Joerideman That looks alright! Just out of curiosity, if you use the bootloader with the default settings (channel, ce/csn assignment), do you see a difference in the debug log?

@Joerideman There is no sign of the bootloader here - can you confirm that your GW is listening on channel 122?

@Joerideman Setting PB2 as output ensures that the SPI runs in master mode which is essential for a correct communication between the ATmega328 and the RF24 radio.

However, after setting PB2 you report:

And now I can use the serial upload :).

which is not related to SPI (serial upload uses the UART interface).

I have watch the MyScontroller Debug window and the messages. But I only see a presentation at some point, and than it is started.

Please provide debug logs / screenshots / whatever you have for further troubleshooting...

@Joerideman I'm not quite sure how setting the master SPI mode should fix the serial upload issue...What exactly are you referring to? Serial upload via FTDI adapter or FOTA (=firmware over the air) update via RF24?

@Joerideman I noticed that you didn't set PB2 as output (see comments) => SPI operates in slave mode. Do you see radio activity on channel 122 after fixing that?

@Joerideman What board are you using? Also, please post the entire SPI communication section from HW.h for full reference.

@BearWithBeard Excellent! Thanks for the feedback. (If your setup/time allows, would be interesting to get your feedback on the ESP MQTT GW with dualRF...)

@monte yes, all transport types are supported

Sensbender, Janus, and HALO - they all support multiple RF modules, but the MySensors framework doesn't...until now

Example of a dualRF Sensebender serial gateway configuration - as simple as that:

#define MY_GATEWAY_SERIAL

#define MY_RADIO_RF24
#define MY_RADIO_RFM69
#define MY_RFM69_NEW_DRIVER // required for multitransport

// optional (but recommended)
#define MY_RF24_USE_INTERRUPTS

Some of the new features:

• multiple transports with RX queue
• GW does radio-specific routing, however, the network is still limited to 254 nodes
• RFM95 radio driver can run in RFM69 compatibility mode

This is still WIP (and will be for a while) but you can already get your hands dirty and test the PR.

Kudos to @scalz (Janus and HALO) and @tbowmo (Sensebender) for their cool boards!

Have fun!

https://github.com/mysensors/MySensors/pull/1414

@mfalkvidd @bjacobse correct, WDT settings are saved and restored - see here https://github.com/mysensors/MySensors/blob/development/hal/architecture/AVR/MyHwAVR.cpp#L92 and https://github.com/mysensors/MySensors/blob/development/hal/architecture/AVR/MyHwAVR.cpp#L116-L119

@andy5211d MYSController won't work with GW debug output. Use the GatewaySerial or GatewayW5100 example sketch to interact with your nodes.

@Technovation It take the blame
Thanks for reporting, PR submitted.

(The debug message is correct; msg contains the incoming nonce request => the sender is the recipient of the nonce response)

https://github.com/mysensors/MySensors/pull/1402

Updated log parser to include RC debug messages: https://github.com/mysensors/MySensors/pull/1396

@Marcell-Gerzsenyi Perfect, thanks for reporting back!

@willemx Excellent! Have fun!

@willemx said in Need help with ESP8266 MQTT Gateway (RFM69HW radio):

450 !RFM69:INIT:SANCHK FAIL

There is a problem with the rfm69 module and/or wiring on your GW - can you exchange the rfm69 module with the one from the node and post the logs?

@willemx Can you try with the new rfm69 driver & debug verbose mode on both, node & gw - i.e.

#define MY_RFM69_NEW_DRIVER
#define MY_DEBUG_VERBOSE_RFM69

and post the debug logs here.

@willemx And you have 868Mhz modules?

@mrhutchinsonmn It compiles here, can you post the entire compilation log?

@matkor like that:

#define MY_CORE_ONLY
#include <MySensors.h>
MyMessage MyVar;

void setup() {}
void loop() {}

@Marcell-Gerzsenyi I've added initial support for the Arduino STM32 core, but things move slowly with limited bandwith. Please feel free to test and report back:

https://github.com/tekka007/MySensors/tree/STM32duinoUpdate

@mrhutchinsonmn Looks like your MySensors library is outdated, please update to 2.3.2

@mntlvr Looks like you're running an older version of the Arduino IDE (1.8.4) - please update to 1.8.12 and give it another shot.

PR submitted: https://github.com/mysensors/MySensors/pull/1392

@macieiks This is triggered by the HA, as the log suggests:

Please check with the HA ppl

@Joost did you set

#define MY_SIGNAL_REPORT_ENABLED

to enable the signal report functionality as documented here?

@rozpruwacz You can call

_process();

however, this is an internal function and may change in upcoming releases.

@alowhum No need to substitute isAck() - it is marked deprecated but remains fully functional in the 2.x code. However, it is advisable to use isEcho() in the future to avoid confusions.

Yet another early holiday gift, MySensors 2.3.2 has finally been released!

Highlights

• Add support for RPI4
• Transport and crypto HAL update
• Rename "soft ack" to echo
• Add log parser
• RF24 improvements

...and many other bug fixes and tweaks

...and a little teaser: 2.4 will come with a set of new features some of you have been waiting for... stay tuned

@encrypt said in Signing fails due to NACKed messages:

I can't enable radio logging easily but I suspect it could be caused by the auto-adjusting RSSI feature...

I'm afraid, but without additional debug information it's gonna stay a guessing game. If possible, enable

#define MY_DEBUG_VERBOSE_SIGNING
#define MY_DEBUG_VERBOSE_RFM69

for additional info. Also, please post the node sketch to interpret the log in the right context.

@chickey @ykhokhlov This was a POC I did a few years ago and never updated the code nor did I do further development on the library due to limited interest. There are way better alternatives available nowadays, i.e. nrf51/nrf52.

@dsiee You have to set the appropriate center frequency for your modules, i.e. for rfm98 use:

#define MY_RFM95_FREQUENCY RFM95_434MHZ

(RFM95_434MHZ = 433.92Mhz center frequency)

@neverdie said in My experiences with MySensors:

Is LoRa even supported by mysensors as yet? It's been a long while since I last checked.

Yes, we support RFM95 radios and various LoRa settings: https://www.mysensors.org/apidocs-beta/group__RFM95SettingGrpPub.html

@pepson Did you add

#include <Ethernet.h>

?

@zen85 This feature is currently not supported in MYSBootloader.

@mkaiser That's a great idea - code contributions are always welcome

@zen85 You have to create a new CE/CSN definition here and adjust the init code here.

@zen85 correct, if the radio pins are different you have to recompile the bootloader.

@magpern One more thing - please re-run the test with my sketch uploaded to your node and adding

#define MY_NODE_ID 100

before the MySensors include, and an unmodified GW serial sketch from the example folder. Please post again both logs here.

@magpern said in Device and gateway see each other, but not regestering:

@tekka

I actually don't think the device and the gateway actively talk. It is more like the Gateway is listening, but not talking.

In your first post you mentioned:

I have altered the device sketch to just have the bare minimum. The gateway works with other devices.

So you can confirm that the sensebender GW communicates with other nodes? I'd like to narrow down the issue to the actual node.

@magpern The issue is still the same: GW seems ok (based on the log and your report that it communicates with other nodes), but the actuator node does not receive a single message.

Please upload this sketch to your node, run it for 10s and post the full debug log of GW & node.

@dirk120 what dev version were you on?

@magpern This originates from the updated Arduino SAMD board definitions (>1.8.1) and is fixed in the dev branch. You can add

#define PRIuFAST8	"u"
#define PRIxFAST8	"x"
#define PRIXFAST8	"X"

before the MySensor.h include to temporarily fix that.

@skywatch Here is a simplified flowchart that illustrates the two most common MySensors bootup scenarios (but as @mfalkvidd pointed out, there are many more possibilities depending on the transport configuration and/or defines):

@danielef alternatively, you can move the setup() code to preHwInit() - this function is called before the any other HW initializes.

@danielef A driver initialization in setup() interferes with the SPI and/or RF24 radio: TSP=0 hints to a failed transport sanity check. I presume you're having radio issues in loop()?

@yveaux Defining MY_RF24_IRQ_PIN does not enable the RX queue feature per se. Therefore it compiles

@mfalkvidd said in MY_RF24_IRQ_PIN on ESP8266 GW:

@sergio-rius if the gateway can send and receive messages, the irq is working.

MY_RF24_IRQ_PIN is currently only used for the RX_QUEUE_BUFFER feature, and unfortunately, ESP8266 does not support interrupt usage for SPI. See comments here: https://github.com/mysensors/MySensors/blob/development/hal/transport/RF24/driver/RF24.cpp#L525

@gerator Looks like a stack overflow - how much RAM is free after compilation? Also, could you try with the latest development branch?

Here is a modified RF24 stack with (among other little changes) a waiting period and no IRQ line (as @Yveaux suggested) for testing: https://github.com/tekka007/MySensors/tree/OptimizedRF24polling

@odritter

Using the previously mentioned sensor board with a header socket, we observed that almost any nRF24L01+ board worked when cabled (~6 inches) rather than directly plugging into the sensor board. (BUT WHY?????)

Is this setup referring to image 7?

@mfalkvidd The Arduino builder generates two .hex files, one of which contains the bootloader as specified in boards.txt. Depending on the flashing settings you may burn the sketch only or the sketch + bootloader, however, the bootloader is not needed for ISP programming.

@encrypt Ok, this explains your issue: programming via ISP will do a chip erase and hence the EESAVE fuse setting is critical for e2p persistance. The most common use case is programming via serial bootloader (e.g. optiboot, atmegaboot, etc.) which only does page erases and leaves the rest untouched. To answer your question: If you're using an ISP programmer you do not need a bootloader.

@encrypt I may have an idea what's going on here: Are you programming a new sketch to your barebone AT328p via ArduinoISP or any other means of serial (=SPI) programming? Programming via bootloader (ATmegaboot or optiboot) requires a FTDI adapter and will only do page erases while leaving the eeprom untouched.

@anticimex @Encrypt That's a bit odd and certainly specific to the bootloader you're using (ATmegaBoot): AVRdude does (at least with optiboot) a page erase (vs. chip erase where EESAVE has an effect). I do not have the EESAVE fuse bit set and no issues with erased eeprom when loading a new sketch, also see below:

Arduino Uno with optiboot:

uno.bootloader.tool=avrdude
uno.bootloader.low_fuses=0xFF
uno.bootloader.high_fuses=0xDE
uno.bootloader.extended_fuses=0xFD
uno.bootloader.unlock_bits=0x3F
uno.bootloader.lock_bits=0x0F
uno.bootloader.file=optiboot/optiboot_atmega328.hex

High fuse (0xDE) does not enable EESAVE.

@mythbai Looks like the node is not actively listening for incoming commands. Please post the full node sketch and node debug log for troubleshooting.

@sirben You can download the library here: https://github.com/tekka007/MySensors/tree/GWonlyHeartbeat

@sirben ok, this feature is currently disabled for GW-only with disabled transport network. I'll prepare a code update: https://github.com/mysensors/MySensors/pull/1273

@sirben Welcome to MySensors! When talking about the heartbeat output - are you referring to the serial debug or tcp/ip output?

@phil2020 Thanks for reporting back. Do you happen to have a full debug log of both nodes incl. GW debug log while assigning ID 255, rebooting and setting new IDs (without random delay) - I'd like to understand why the random token verification failed.

@phil2020 After assigning ID 255 you need to power cycle the node to trigger a new ID request (only for non-static ID defs)

@bearwithbeard Your bare at328p runs at 8Mhz [intRC] but you compile with 16Mhz settings (according to platformio nanoatmega328 boards). You may resolve your issue with e.g. pro8MHzatmega328 settings (3V3, 8Mhz). Ideal baudrate 38400 or 57600.

@bearwithbeard What board settings did you choose for compilation?

@mrumpf Thanks for your feedback - just for reference, did you try the BH1750FVI library and the sensor init code in preHwInit()?

@mrumpf From the GW log:

21822 MCO:BGN:INIT OK,TSP=0

I see the RF24 sanity check failing and this is likely due to the BH1750 initialization code meddling with the RF24 SPI. Most probably you can fix the issue by moving the sensor setup code to preHwInit(), i.e.

This also explains why the GW "recovers" after 930000ms ~= 15mins, which happens to be the GW transport sanity check interval followed by a successful transport re-init:

920856 !TSF:SAN:FAIL
920859 TSM:FAIL:CNT=1
920863 TSM:FAIL:DIS
920867 TSF:TDI:TSL

930876 TSM:INIT
930884 TSM:INIT:TSP OK 

@hek Is there a pic-only limitation with the file uploader?

@mrumpf said in Broken gateway with local sensors on MQTT ESP8266 GW:

Here are the logs.
Again, after 930000 seconds the gateway did a re-init and after that the 2 devices could communicate.
[0_1551388989628_Archive.zip](Uploading 100%)
Uploading a file gives me an error that only image types are supported!?

@mrumpf Could be a power issue or one of the included libraries interfering with the SPI. The full debug log (from the beginning) may give additional hints - please upload them here (as .zip)

@mrumpf Can you share more details about your setup & sensors used, also posting your sketch and the full debug log are a good starting point for troubleshooting.

@njwyborn Can you post the GW sketch that fails in your setup - did you also try with the 2.3.2-dev branch?

@anticimex indeed, seems to be a stack issue - see milliseconds counter before the GW reboots:
0;255;3;0;9;26878 SGN:BND:NONCE=0E92DADC44930DBA963AE05F948FCBCAAD56AD406929AC6E67AAAAAAAAAAAAAA

0;255;3;0;9;0 MCO:BGN:INIT GW,CP=RRNGAS--,REL=255,VER=2.3.1

Bingo! This is a backwards incompatibility - thanks for reporting!

@joaoabs You should be able to fix this by using the SecurityPersonalizer example from the 2.3.1 lib and copy/paste the settings section from your current sketch to the example sketch.
@Anticimex issue originates from replacing all signerSHA256xyz() functions in the cryptoHAL

@snyfir Can you run the same tests using the latest release, i.e. 2.3.1?

@m3nt4lll if the modules are 433Mhz you can use the pre-defined RFM95_434MHZ setting (center frequency is 433.92Mhz)

@m3nt4lll Are you using 868 or 915Mhz modules? How are the IRQ lines connected?

@berkseo Nice board and idea - would you mind posting your pcb layout files and testing sketch for the community?

@flopp yes, GW sketch + log, and if possible, from a node that stops sending messages

@flopp Please post the full debug log + sketch for further troubleshooting

@mfalkvidd Strictly speaking, only @Yveaux's solution would work without modifications to the MySensors core But the challenge was weakly defined, so no cheating in that sense

@alowhum Instead of a timer, the watchdog interrupt is used to set a flag on a (in this sketch) not-used eeprom addressing register (EEARL)...certainly not a generic approach, but functional

@Yveaux @mfalkvidd Now it gets ugly - and we are not talking ASM yet...

ISR (WDT_vect) {
  WDTCSR = _BV(WDCE) | _BV(WDE); 
  WDTCSR = _BV(WDIF) | _BV(WDIE) | 6; // 1s
  EEARL = 1;
} 

void setup() {
  WDT_vect();
}

void loop() {
    if(EEARL) {

      // ... code that runs every second...

@fausti Can you re-test your setup with this patch (ideally, update GW and nodes): https://github.com/tekka007/MySensors/tree/RF24STDBYTiming - I've added a delay after setting the radio in standby mode.

@fausti the log indicates that smartsleep is enabled - that said, smartsleep may originate from the nodemanager

6047 MCO:SLP:MS=20864000,SMS=1

FYI: I tried with both, 2.3.0 and 2.3.1-beta (incl. CE fix), on non-amplified and PA+LNA modules - I do not see any delay between TSB and SEND

6973 MCO:SLP:MS=5000,SMS=1,I1=1,M1=1,I2=255,M2=255
6979 TSF:MSG:SEND,100-100-0-0,s=255,c=3,t=32,pt=5,l=4,sg=0,ft=0,st=OK:500
7486 TSF:TDI:TSL
7487 MCO:SLP:WUP=1
7489 TSF:TRI:TSB
7492 TSF:MSG:SEND,100-100-0-0,s=255,c=3,t=33,pt=5,l=4,sg=0,ft=0,st=OK:5000

I assume you have a power issue, a bad module - or an artifact originating from the nodemanager?

...but, the delay between TSB and SEND is a bit odd;

9480 TSF:TRI:TSB
11180 !TSF:MSG:SEND,9-9-0-0,s=255,c=3,t=33,pt=5,l=4,sg=0,ft=0,st=NACK:20864000

Enabling MY_DEBUG_VERBOSE_RF24 could eventually give some hints.

@mfalkvidd @fausti no, this is normal the smartsleep log:

6047 MCO:SLP:MS=20864000,SMS=1,I1=1,M1=1,I2=255,M2=255  

==> smart sleep enabled, IRQ on pin 1 set, going to sleep for 20864000 ms

6125 TSF:MSG:SEND,9-9-0-0,s=255,c=3,t=32,pt=5,l=4,sg=0,ft=0,st=OK:500 

==> I_PRE_SLEEP_NOTIFICATION, 500ms to process any incoming message before going to seep

6199 TSF:MSG:READ,0-0-9,s=2,c=1,t=23,pt=5,l=4,sg=0:5
6254 TSF:MSG:ACK
6699 TSF:TDI:TSL
6717 MCO:SLP:WUP=1
6735 TSF:TRI:TSB

==> sleep interrupted by IRQ 1

8437 !TSF:MSG:SEND,9-9-0-0,s=255,c=3,t=33,pt=5,l=4,sg=0,ft=0,st=NACK:20864000

==> I_POST_SLEEP_NOTIFICATION, node was sleeping for 20864000ms (but sleep was interrupted)

@titvs Would be great if you collect the debug log of the repeater, especially when the NACKs happen - this may help to understand the origin of the issue
