wemos d1 pro mini periodic exceptions (unstable) #6520

Closed afagard closed 5 years ago

afagard commented 5 years ago

I've got an off-brand Wemos D1 mini pro off Amazon.

I made a script that works fine on a regular Arduino but results in period exceptions that are always different on the wemos. So I thought, ok, maybe my code is the problem, maybe some library I was using wasn't "compatible". I then tried various example sketches that were installed along with this repo. Notably, the "hello server" one. And am facing the same issues, although the exception is almost always 0.

Raw trace:

Exception (0):
epc1=0x4023a054 epc2=0x00000000 epc3=0x00000000 excvaddr=0x00000000 depc=0x00000000

Could this be hardware related failure? I am hoping so, otherwise this ESP ecosystem is kind of a pida given the stack traces (at least to me) don't seem that informative. Especially if they have a tendency to change with the same code making it difficult to debug.

Things I've tried:

Power: My system is supplied with 12 volts from an adapter (also tried computer PSU), which is then stepped down to 5 volts and then fed in to the Wemos D1 5V in.

I ordered a LOLIN Wemos D1 mini pro off Amazon so I have something to test against but it isn't here yet.

When you opened this issue you were presented with an issue template with specific instructions and requiring specific info. You completely ignored it. Closing due to non-compliance.

BTW, you haven't tried the most important thing of all: latest git.

#6366 (comment)

I read that comment, that is why I double checked my power supply. It is 12v to a 5v buck converter, then direct to the wemos board. Surely that couldn't be the issue? It isn't powered off USB or some voltage divider from a TTL adapter.

Will definitely be trying to lower the output wifi power to 16db as suggested.

Is this correct: WiFi.setOutputPower(16);?

UPDATE: Currently been running problem free for an hour. If this was indeed the problem, was it due to some sort of EMF? Noticed that in the nodemcu the esp is canned whereas in the wemos it isn't.

Understandable. I apologize.

Basically the flash chip on the off-brand D1 can't cope with 40mhz and needs to run slower. Turns out this was the real problem I was having... RFI was just making it worse.

Yea. I returned the off-brand one and got a genuine lolin d1 mini pro and haven't had a problem since ;)
