AT+CWJAP returns ERROR
Posted: Fri Dec 04, 2015 6:14 pm
As the title says, I cannot get CWJAP to work correctly. All it returns is an error regardless of what I do. I have the esp 03 that I got of eBay. It came with Ai-Thinker 1.1.1 firmware I believe and now it is on AT version:0.51.0.0 / SDK version:1.5.0.
That is everything I have done in the past couple days. I am perplexed on how/why this is happening, it makes absolutely no sense? I ordered an esp 01 today because this esp 03 has been nothing but garbage for me. I will see how the esp 01 works with my setup when I get it, but for the meantime any ideas on what else I can try to get AT+CWJAP="", "" working? Thanks guys.
- I am on cwmode 1 and I have tried 2 & 3 as well, but 2 gives an error regardless. Worth a shot though.
I have tried the original firmware and the newest update and both returned ERROR for the AT+CWJAP="abcd", "1234"
I have tried adding capacitors to my circuit, that didnt work.
I'm using an ATX bench power supply to supply the 3.3 volts, so current is not an issue nor should voltage fluctuations be.
I have tried putting GPIO2 & GPIO0 to HIGH and also floating, no difference.
I tried to completely wipe my flash using esptool.py and reflash. No difference either.
AT+CWLAP works fine, no problem. AT+CWJAP? returns No AP. Every other AT command works except AT+CWJAP="", ""
I have been searching Google for 2 days and nothing similar comes up, seems I am the only one with this error.
