@mfalkvidd Yes you are correct. The point was that digitalPinToInterrupt(MY_RFM95_IRQ_PIN) makes everything works on the D1. Leaving digitalPinToInterrupt() out will break the gateway.

@mfalkvidd It was code from my ESP RFM69 gateway. Runs on NodeMCUV3. But that works perfect. But I may reflash that one with the good define code.

But the example in your link seems wrong.

#define MY_RFM95_IRQ_PIN DEFAULT_RFM95_IRQ_PIN

Should be

#define MY_RFM95_IRQ_NUM digitalPinToInterrupt(MY_RFM95_IRQ_PIN)

To make it working on an ESP8266 Wemos D1 Mini with RFM95 radio.

@electrik OMG, this was a quick fix! It runs very good.

Thank you all for the help als reading. Very nice!

Hello MySensor Friends!

I got myself a new challange. Wiring up an RFM95 gateway so I can reflash my buggy LORA Soil Sensors with RFM95 radio's and put it to work in my trusty MySensors environment.

Everything is being built with the latest Mysensor branch (2.3.2).

Gateway Sketch is straight forward, just like the Node sketch.

Now what is the problem. The Node sends out a parent request (PARENT_REQUEST) The gateway even responds to this request (To Node ID). But the node is not getting that message at all. It looks like there is one way traffic. Or None.

What did I do?

On the gateway I enabled the following options (extra)

#define MY_RADIO_RFM95
#define MY_RFM95_FREQUENCY (RFM95_868MHZ)
#define MY_RFM95_MODEM_CONFIGRUATION RFM95_BW125CR45SF128
#define MY_RFM95_ATC_MODE_DISABLED
#define MY_RFM95_TX_POWER_DBM (13)
#define MY_TRANSPORT_STATE_TIMEOUT_MS (3*1000ul)
#define RFM95_RETRY_TIMEOUT_MS (5000ul)
#define MY_DEBUG_VERBOSE_RFM95

And on the node I did the following

#define MY_RFM95_MODEM_CONFIGRUATION RFM95_BW125CR45SF128
#define MY_TRANSPORT_STATE_TIMEOUT_MS (3*1000ul)
#define RFM95_RETRY_TIMEOUT_MS (5000ul)
#define MY_DEBUG_VERBOSE_RFM95

If I collect al the different logs and put them in the Log Parser I can see that the Node request is recieved by the gateway. The gateway then send a response. But the node is not getting it.

I'm out of ideas. Moved the node arround the house. Looked at the schematics.
It is a busy spectrum here at 868mhz. I still have an RFM69 mysensors gateway, a lora gateway and Z-Wave all fighting over 868mhz.

The stuff I'm using
Gateway:
A Wemos D1 Mini with an RFM Shield from Diycon (https://diycon.nl/product/d1-rfm-shield-pcb301-for-rfm-and-wemos-d1/) I soldered an extra 10 uF capacitator on the shield for stable 3.3 volts

Node
A Makerfab soil sensor with RFM95 radio (v2) (https://www.makerfabs.com/lora-soil-moisture-sensor-v2.html)

If anybode has an idea. Please let me know.

Success!

I've been reading and measuring and soldering everything to fix the bug. With some datasheet help and my trusty multimeter. I did the following fix:

Soldering the SCK pin (only soldering this pin does not fix the CRC errors)
Soldering pin 7 to pin 8 on the flash chip finishes the fix.

So first my log shows:

OTA:FWP:FL DUMP 437A:0000000000000000000000000000000018530 

Now the log shows

TSF:MSG:READ,0-0-45,s=255,c=4,t=3,pt=6,l=22,sg=0:03000D0003000C94D5030C94D5030C94D5030C94D503
OTA:FWP:FL DUMP 003A:0C94D5030C94D5030C94D5030C94D503127516 

Lot more data is whriting to the flash.

And after the firmware is recieved:

127760 OTA:FWP:FW END
129652 OTA:CRC:B=04E0,C=3E27,F=3E27
129656 OTA:FWP:CRC OK

And the node reboots so OTA works!

And as a bonus

#define MY_OTA_FLASH_JDECID (0x1F65)

Works also so this can also be used as an red flag if your OTA is not working and you have the correct flash chip but get a FLASH INIT error.

I would like to thank everybody for helping!

@sundberg84 I would not move away from your great PCB design, but I might order some new ones.

Okay, i understand there are some bugs in the PCB design. Having V10 boards I have tried to do a quick fix and solder the SCK pin.

But still getting CRC errors. Should I do more more modifications? Or abandon the EasyPCB boards because of the bugs with the flash memory and get some other PCB to try again?

@sundberg84 And the bug is that the SCK pin is going nowhere? Because that pin is not connected to SCK in the schematic.
@cabat Alright so the messages are correct but the flash is not working.

So my next step is to solder the SCK pin. Will do that in a few days. Keeping everybody in the loop.

Maybe replying at my own post.

But the MySensors OTA code uses

#define MY_OTA_FLASH_JDECID (0x1F65)

That is for the AT25DF512C-SSHN-B if i read the datasheet from Adesto right. But using code 0x1F65 always results in Flash INIT error and using 0x00 works. But that's the "unknown type".

OK,

Now I'm seeing

125540 OTA:FWP:FL DUMP 000A:00000000000000000000000000000000125546 

These lines in the serial console and a lot of them. Don't know if these lines are any good.

18442 OTA:FRQ:FW REQ,T=0003,V=000D,B=0437
18466 TSF:MSG:SEND,45-45-0-0,s=255,c=4,t=2,pt=6,l=6,sg=0,ft=0,st=OK:03000D003704

18524 OTA:FWP:FL DUMP 437A:0000000000000000000000000000000018530 

It get's a long line from recieve and just a small amount reads from flash?

Yes I've seen MyOtaFirmUpdate.h and the log messages.

Did some calculations on the B/C and F line

109953 OTA:FWP:FW END
111788 OTA:CRC:B=04E0,C=5897,F=3E27
111792 !OTA:FWP:CRC FAIL

B= Firmware Blocks, 1248 blocks (same value from MyController)
F= Firmware CRC 15911 (same value from MyController)

No the wrong one:
C= Calculated CRC 22679 that divers from Mycontrollers 15911 value.

But I can't figure out what causes these calculated crc errors. Well I know how CRC is calculated, but now how do I figure out where the error is happening.

Hi Everyone,

As a some sort MySensors enthousiast I can't get OTA to work (ever).

I have a current setup with a Raspberry Pi 3B that is configured with an RFM69 radio and setup as MQTT gateway. I have multiple nodes setup and with MQTT is all works flawless.

So last december I wanted to take it to another level and get my nodes to OTA, but as of today I can't get it to work.

Anyway to make my nodes OTA I installed mycontroller.org and set everything up. I use EasyPCB boards with RFM69 radio's, and soldered AT25DF512C-SSHN-B on these boards. Burned the Dualoptiboot sensebender micro bootloader as instructed.

Started with a simple battery node (code from examples and added OTA).

Only to change the version number in presentation and compile and upload the HEX file to MyController. Instructing the node to upload the firmware always results in CRC error.

Node log using serial console:

178499 OTA:FWP:FW END
180334 OTA:CRC:B=04E0,C=5897,F=3E27
180338 !OTA:FWP:CRC FAIL

My question. Is there anybody how has this some problem? Or is having the same setup and do have a working OTA environment? I'm running Mycontroller 1.5.0 FINAL and Mysensors 2.3.2 code on both the node and gateway. And not having any luck using OTA. All the rest works as expected. Did found a lot of other topics but these where all old and fixed in later firmwares.

Thanks in advance.
