0.9.6_b1 - "ready" not found after changing the baud rate

Postby MicKey » Fri Mar 06, 2015 5:16 am

Hi,
I'm trying new firmware 0.9.6_b1 and after changing the baud rate by "AT+UART=9600,8,1,0,0" and reset, I can not find "ready" at any baud rate.

9600Bd:

Code: Select all

˙<0> ţ0ř0‚Bî8<0>Ë@<0>ţZHH•…‘ĺ5

and then responds to AT-commands.

115200Bd:

Code: Select all

Then,

Can it response “OK” after you input “AT” ?

can it still work as usual ?

Yes, it responds at 9600Bd:

Code: Select all

AT+RST


OK
Z÷úˇ0'ŠĆâcAÁP<0k¤óZHH•…‘ĺ5AT


OK
AT+GMR

AT version:0.22.b1.0
SDK version:0.9.6(b1)

OK

I can wait for "ready" with a timeout and then try to send AT.
But I think it's just a workaround.

THX,
Mic

"If it does not work, you need to re-download AT firmware to your module to recover."
