mDot-EVB AT Commands

[Shankar Bandaru]

Hi,

We just got the UDK with mDOT & EVB. The mDOT on board with UDK works fine and takes AT Commands, joins network. With the EVB connected to UDK with 9 pin cable supplied it doesn’t take any AT Commands.

How to fix this, I am not able to change the network/passphrase params to join the network.

Thanks,
Shankar.

Hi Shankar,
We’re about to release new dotbox firmware that supports AT commands. The documentation is up on multitech.net and quick start guides have already been written, which is why you might be confused.

When the firmware is released, it will be available on the multitech.net downloads page. It should be coming in the next week or two.

Cheers,
Mike

Hi Shankar,

On the UDK the UART used for AT commands is on the XBEE_DIN/XBEE_DOUT while in the case of the MTDOT-EVB the USBTX/USBRX pins are used.

I was able to get the AT commands working by making the following change to the mDot_AT_firmware:

#define IS_MDOT_EVB

#ifdef IS_MDOT_EVB
mts::MTSSerial serial(USBTX, USBRX, 512, 512);
#else
mts::MTSSerial serial(XBEE_DOUT, XBEE_DIN, 512, 512);
#endif

Hopefully that helps,
Shaun

Hi Shaun,

I have updated with the new firmware and all seems to work fine. Thanks for your answer, it is helpful.

Shankar.
