Hi

Very easy to overlook when a "PC" is taking care of everything as you don't get to see what is going on behind the scenes. Not so with a uC though

Hi If you reread my answer (# Two) you will see that I inform of what a server expects and what we need to do to achieve this. Only sending part of the required string is very unlikely to achieve results and hitting the enter key before you have sent the entire command will cause the esp to attempt ...

Hi You posted three screenshots. One The "empty" macro you refer to is just an example. You would instead add whatever macros you need to gather whatever data you desire. Two We are using AT commands to control the esp8266. If you refer to the AT Commands and look at CIPSEND you will find out how it...

Hi

The Wiki has some examples that are very helpful.

Hi No access to FC / hardware at present. Good afternoon! I'm sorry, maybe you misunderstood me or I didn't understand you. When information is transmitted from one esp-01 module to another of the same module without using an external router, do these esp-01 modules create a network among themselves...

Hi Sorry, I've no access to the actual files at present. I used an internal oscillator for the PIC microcontroller. It has an inbuilt stable oscillator that can be selected. OSCCON is the register and 0xF0 would be the setting for the chosen speed. Each PIC may be different. Using the internal oscil...

Hi

Have a read

Although not your target chip, the principles are the same. In the posts two ESP8266 chips send data to each other in two ways. The first uses existing WiFi router, then they talk directly.

Hi I was a bit busy this week, catching up over the weekend. As mentioned before, Flowcode interacts with the ESP8266 using the "AT" commands and you can monitor commands / responses using your USB-TTL Serial convertor (more on this later). This also means you can use your PC to interact too, just b...

Hi I'm a little busy for the next day or so but when I get a chance I'll send links to examples you can follow. One quick question though, will the building have its own WiFi infrastructure (i.e. a router providing WiFi internet access throughout) or will the modules need to create their own point-t...

Hi Now I understand a bit better. If so, what you want is the ability to have: Multiple sensors throughout building Each sensor is "managed" by a microcontroller (each microcontroller may have multiple sensors) Each microcontroller will gather data and send to a "receiver" microcontroller This recei...

Hi I would hope any future firmware upgrades would be done in a similar manner but as none have been released in years it is unlikely you will need to do so again. Everything from now on just operates by sending specific AT commands which is why I recommend you download a copy. The ESP8266 modules, ...

Hi

You are welcome.

Hi I am so very glad to hear that and it is indeed now becoming a happy holiday. Well done in getting it working :D The issue seems to be that they license out manufacture which means anyone with a license is then responsible for all documentation as it is essentially now their product. To compound ...

Hi The interface assignments are redefined so basically we have no UART access at all unless we put it into Flash Mode. No need to erase, just select the files / addresses and ensure the necessary checkboxes are ticked etc and flash as before but using DOUT. Admittedly a long shot...... I'll look at...

Hi As mentioned before, info on these components is hard to gather, but from some posts it is suggesting that certain modules won't handle later firmware as the UART pins change. They mention you can possibly modify the firmware and reassign pins, but I have no experience of this. The posts inform t...

Hi

I ask as the check boxes on the left aren't checked on v2.3

Regards

Hi

Just to be clear, after you erased you then flashed using flash tool 2.3 as before?

Regards

Hi My log files are different to yours and I now know why. The only way I can replicate logs similar to yours is if I skip steps. If I open Flash Tool then download straight away, not testing first or double checking values and selecting files, then I get a log similar to yours (Flash tool remembers...

Hi

I have the feeling that we are overlooking something simple, which is why I'm asking "stupid" questions as many times I've overlooked something simple.

I might not get a chance to compare logs tonight, but I will when I get the chance.

Regards

Hi

Again, stupid question. Did you reset the esp and close Flash?

Regards

Hi No real need to unplug the adapter but you do need to close the flash tool and also reset the esp. There is a slight chance that when you unplugged the adapter and then reinserted it assigned a different port (unlikely) but if you hadn't reset (or removed power then repowered) the esp it would st...

Hi I'll compare against mine later tonight. If it is jumping to DIO by itself then it is overiding the setting of QIO as SpiAutoSet is checked. Not sure why it is choosing DIO over QIO. Maybe try it without SpiAutoSet checked? Stupid question time (as in your earlier post it did look as though you l...

PS

Try using QIO for SPI Mode, not DIO

Hi

Unfortunately a screenshot of a partial log isn't of much help here.

Can you copy the log and paste into a text / word documents and send that?

Regards

Hi That's good you are getting the responses documented in your post. You are almost there. You forgot however to enter the correct Hex values in the Address boxes File / Hex Address blank / 0xfb000 esp_init_data_default_v08 / 0xfc000 blank / 0x7e000 blank / 0xfe000 boot_v1.7 / 0x00000 user1.1024.ne...
