- Sat Oct 04, 2014 1:17 pm #1183 Here's where I'm up to - and I understand the delay issue - I'm just ensuring that the entire buffer is emptied. I'm getting to see the list of routers - but no matter what I do or how long I want - it won't connect - indeed I get ERROR fairly quickly.

Here's the sequence including messages to the second serial port (I'm using a 1284 chip with 2 uarts) - as you'll see - list of APs no problem - but won't connect despite passport being correct

- Sun Oct 05, 2014 10:48 am #1240 You'll need to wait longer after the AT+CWLAP: wait until it completes (i.e. with OK or ERROR), only then send AT+CWJAP. As you may observe, you never receive OK for your AT+CWJAP, only a "busy now" which indicates (somehow) that the device is still busy and has dropped your command.
