ESP32

[Alan_37]

Hi, I have been playing with Esp32, and if I am not doing something wrong the following are bugs.

1, The quad encoder Post Scaler 1:4 does not work it always returns 4 steps at a time.

2, If putting an OR statement in a loop will not compile to hex.

3, for some strange reason sometimes ( not always) when using local variables, will cause failure to compile ( then use global and compile ok)

4, MQTT read timeout does not work Setting it 50ms it stops there until a message is received after 1
a minute or so if no message is received will exit and will not work again.

Hi,
Thanks for the post.
Would it be possible for you to give us some examples?
These look like very specific scenarios that we might not have enough information to replicate.
For example, OR is a bitwise OR, so might not be suitable for your situation.
Thanks

HI ,

So the loop bug example -> Loop until: var1 = 100 OR var2 = 200 .

As for the MQTT read timeout, this is very important cos it stops all the code from executing
I was able to work around the problem of it stop receiving by doing a disconnect and connecting again
every time I run the Read.

but it still hangs there waiting.

Hi,
Try this instead

Code: Select all

(var1 = 100) || (var2 = 200)

I'll have a chat with Ben re the IOT bug on Monday, it's his wrap on my MQTT Client.

Thanks, looking forward for the fix .

Hi Ben, Thanks for your reply

No, it does not work, the led does not blink because the read timeout is not working
and the esp is stuck waiting for the MQTT message.

After some time led starts to blink but then it does not receive MQTT messages anymore
then it connects again and stops there waiting again.

I can still ping the esp and my MQTT server is also pingable.

I have a question,

Does the free ESP32 chip pack have limited support or offered as is ?

Hi,
Could you please try the attached updated file, to go into C:\ProgramData\MatrixTSL\FlowcodeV9\CAL\ESP
Thanks

Hi LeighM, Thanks for your reply

I have replaced the file now the read timeout seems to be working but
now the ESP is not able to receive or send any messages from/to the MQTT server .
