MYSBootloader 1.3 pre-release & MYSController 1.0.0beta

Anduril

@tekka I only copied the standard fuses (no 1/8 divider) and I think it is running on 16Mhz. Might be good to try with different baudrate for the 8Mhz version.
But still, do you know why the OTA transfer is slower by a factor of 3?
The sketch for my current project is quite big and needs several minutes to transfer. With serial upload working this would be much faster, but I have to unplug the nano from the circuit to reach the usb port. So fast OTA upload would be best.

@Anduril I had problems with 8MHz with 3,3V and 115200kBPS. I only use 38400kBPS with my 8MHz nodes. (Of cause your Bootloader must also be set to the same Baudrate as specified in the board.txt, they must match, i.e. you cannot just change the Boards.txt and have another Baudrate for programming.)

I'm not sure if @tekka is providing a Bootloader hex file with 38400kBPS and 8MHz. From his first post I'm assuming he ueses a 57600kBPS with 8MHz. This might also work, however 57600kBPS with 8MHz introduces a baud rate error of 3.5% which sometimes causes problems with my PC/FTDI Dongle. So I personally use 38400kBPS which only has 0.2% Error: http://wormfood.net/avrbaudcalc.php (fosc=8MHz)

Hi. @tekka thanks for your works, OTA fw updates works very well (using MYSBootloader 1.3pre), but i've one question, after OTA updates successful and node running the sketch without error, how to update the fw using new ones? e.g an updated version of the sketch.
I'm using MyController.org for controller by @jkandasa . So I ask to both of you.

thanks.

@Anduril a factor 3 slower is a bit surprizing, in my hands the new bootloader performs even better than the old one. Do you have a repeater in between or are GW and the node close together? As @Dirk_H pointed out, the current .hex was compiled for 16Mhz (and is also compatible with 8Mhz) but I
will prepare a separate 8Mhz version and 38.4kBaud for testing.

Hi,
I have just started to update all my nodes to 2.0.0 dev.
Started to update my serial gateway then update MYSController to 1.0.0beta and use the bootloader MYSBootloaderV13pre.hex
First i could't burn the bootloader to my Arduino Pro Mini 5v, needed to changed the values in board.txt:
From this:

proMYSBL16.bootloader.low_fuses=0xFF
proMYSBL16.bootloader.high_fuses=0xD2
proMYSBL16.bootloader.lock_bits=0x3F

To this:

proMYSBL16.bootloader.low_fuses=0xF7
proMYSBL16.bootloader.high_fuses=0xDA
proMYSBL16.bootloader.lock_bits=0x0F

It took about 50min to use OTA to upload a simple sketch for a humidity sensor with MYSController.
I have the gateway and the sensor very close (about 10cm from each other).

tekka

@ErrK Fuses have to be adjusted according to HW specifications, e.g. crystal vs. internal RC oscillator settings etc. Your new high fuse (clearing EESAVE) cleared the node settings in the eeprom after flashing the new bootloader (did you use your node as GW before?). 10cm between node and GW is far too close causing radio interferences - you may get better results by moving them further away.

ErrK

@tekka Thanks. It's working when i move them further away.

Anduril

@tekka did some testing again. I don't have a repeater inbetween, but maybe they were to close to each other (~30cm).
I repeated the tests a few times:
when on my desk the new bootloader is significantly slower than the old one.
When 2m away I don't see many messages arriving. Maybe my power suply used when not at my pc was not stable enough to give the current for sending with pa-lna. I will repeat the tests with a improved setup the next days.
Can I give you specific information where the problem is? Maybe a special log or anything else to help find the problem?

tekka

@Anduril hmm...I'm not experiencing any speed issues with the new bootloader. Can you activate debug on your GW and post the log while running OTA updates?

Anduril

@tekka here the serial monitor while OTA upload with #define MY_DEBUG

@Anduril There are some communication issues here, i.e. the node radio doesn't not appear to receive msgs. If you put GW and node further away, different position, away from interference sources (wifi, speaker, monitor, etc.) do you see any improvements? Also you should try with different radios, larger caps, decoupling caps, stable PSU or batteries. What type of nRF24 are you using? Genuine, Clones (blob-version?).

Anduril

@tekka I tried a few combinations: different positions (nearest ~20cm, farest ~5m with walls), radios (probably clones, but no blobs, nRF from mysensors store and others, also pa+lna for gateway) and different caps with no success. Still quite a lot of packages lost during transmision.
I then reflashed the old bootloader again and it worked flawless for 5m and 20cm.

tekka

@Anduril Can you re-test this version of MYSBootloader (16Mhz, CH76, 250kbp) with the most recent dev 2.0.0 version (i.e. GW), clearing EEPROM before flashing is advisable. In my setup, I get pretty decent data rates for OTA updates...

Anduril

@tekka I will test this asap (hopefully this weekend). One point for clearing EEPROM: do you know if the sketch also works on the ESP8266? Because I thought to have cleared the EEPROM and uploaded a sketch without wifi config, but it still connected to my wifi.

Anduril

@tekka I did test your new bootloader, with no success. I also tried to use the nano with 8Mhz internal clock, but same result.
Here again the serial debug of my ESP8266 gateway:

And to note something I noticed (but don't know if it's related): sometimes the MYSController loses it's connection to the gateway. Serial monitor is still printing values but nothing in MYSController. When I reconnect the Controller it is working again.

edit: and is it normal that a sketch needs more than 20 min to upload? I mean the sketch is quite big (>70% of max), but it seems to be to long even with the old (for me faster) bootloader.

edit2: one hour and about 24k messages (MsgID in MYSController) later my node is still updating...

Did any one able to make this work with atmega328p-PU 28 DIP 8MHz internal clock? or is it just me having problems with this boot loader?

I was able to load the boot loader successfully and able to upload a sketch but then nothing happen, i see nothing in the serial port (default 115200) and the gateway does not find any node.

I am using latest dev branch of 2.0 and the boot loader from this thread.

Just for compression i loaded another boot loader for 8MHz internal clock (Arduino on breadboard) and uploaded a sketch to it and it worked perfectly communicating with the gateway.

I want to be able to upload OTA.

AM i doing something wrong? does this boot loader even supports this MCU?

abmantis

I have a node with the NRF already soldered. Since Arduino as ISP uses some of the pins used by the NRF, is there anything I can do to flash the bootloader without unsoldering the NRF? Thanks!

@abmantis You can just solder ISP wires to arduino without disconneting NRF. It's programming well (I've already tested this solution with my network)

abmantis

@Алексей-Гусаров Thank you! Will try that soon :)
Any updates regarding the bootloader?
