I am using a aliexpress board it doesn't have any pull up resistor on uart line

Implement it and u should be good

should I go with 10K one?

segfaultdev.elfOP•11/9/24, 8:15 AM

i doesn't have a bit low value like 4.7k one

Ssegfaultdev.elf should I go with 10K one?

Renuel Roberts•11/9/24, 8:18 AM

Yea its okay

RRenuel Roberts Yea its okay

segfaultdev.elfOP•11/9/24, 8:19 AM

not fixing the issue

Renuel Roberts•11/9/24, 8:19 AM

But if u issues like electrical noise or instability surfaces the solution would be d 4.7k

segfaultdev.elfOP•11/9/24, 8:20 AM

maybe 4.7k is needed

Ssegfaultdev.elf not fixing the issue

Renuel Roberts•11/9/24, 8:20 AM

Then I think u really need d 4.7k

Ssegfaultdev.elf maybe 4.7k is needed

Renuel Roberts•11/9/24, 8:20 AM

Yea

segfaultdev.elfOP•11/9/24, 8:20 AM

adding two 10k in parallel should do the job

segfaultdev.elfOP•11/9/24, 8:20 AM

since it will be 5k

Renuel Roberts•11/9/24, 8:21 AM

Not done this b4 but u can try it out and see if it does

RRenuel Roberts Not done this b4 but u can try it out and see if it does

segfaultdev.elfOP•11/9/24, 8:24 AM

still the issue remains

segfaultdev.elfOP•11/9/24, 8:27 AM

I think the behavior is kinda normal

Ssegfaultdev.elf still the issue remains

Renuel Roberts•11/9/24, 8:44 AM

Did u add d logic to filter out the unexpected/garbage characters

segfaultdev.elfOP•11/9/24, 8:50 AM

RRenuel Roberts Did u add d logic to filter out the unexpected/garbage characters

segfaultdev.elfOP•11/9/24, 8:53 AM

it is happening as i hit the reset button

segfaultdev.elfOP•11/9/24, 8:53 AM

there is no code to run at that stage

Renuel Roberts•11/9/24, 9:02 AM

Is ur pull up resistor closed to ur uart input pin

ZacckOsiemo•11/9/24, 9:22 AM

is it corrupting anything or just spurios noise on power cycle?

segfaultdev.elfOP•11/9/24, 9:23 AM

noise on power cycle

Ssegfaultdev.elf noise on power cycle

ZacckOsiemo•11/9/24, 9:23 AM

have you read the datasheet, go through that power up and power down sequence again

ZacckOsiemo•11/9/24, 9:24 AM

There could be some work happening during power cycle that you may not be able to change

Here's a discussion where you'll find it worked with core version 2.0.6. Please follow the entire conversation https://github.com/espressif/arduino-esp32/issues/6876. It seems to be an issue with the HC-06 & library version conflict

@Ready to Work, a couple updates:

The Assembly job "req" I posted earlier this week is still being defined. They said they should have answers on Monday, at which point I'll share more with those who indicated they were interested in the position.
We're partnering with @Marcweb of Webster and Webster on jobs and @JoeSchneider's firmware org Dojo Five has some positions open. You can find more from both in the #jobs channel.

Hello every one i have little problem about scada system on panneaux solaire the problem is i wanna make another interface to show information from server ..
So we used here serial comminecation rs485 modbus
And i can get addressage of All information like exp when i recive 62800 i kn its for curant or voltage and so on ..
So the qst is how to mapping all address i kn with the new one like i kn 62800 for voltage but voltage update each second for exp

addalaabderrahim•11/9/24, 2:58 PM

So i wanna mapping the new information with old address to know this info for voltage

Hi, could you try rephrasing your question I struggle to understand the issue.

segfaultdev.elfOP•11/9/24, 6:25 PM

I am confused between uni-T 61E+ and ZOYI ZT-703s can anyone help me with their suggestions?

Umesh Lokhande•11/10/24, 5:17 AM

Hi @addalaabderrahim, if you mean that your Modbus address is 62800, which you use to receive voltage information, then the address for reading voltage will not change. Each Modbus address corresponds to a specific parameter when read, and the data size (whether it's 1 byte or 2 bytes) depends on the documentation's mapping of addresses and their respective parameters. I recommend reviewing the documentation to understand the expected data format for each address. Personally, I follow the sequence of addresses to interpret the data received from Modbus. Hope this may help you, best wishes!

addalaabderrahim•11/10/24, 6:14 AM

Ah yes yes thx man ,i will try mapping all adress and if i get problem i will ask

haha
