Help with Basic Command about protocols

[jasondaming]

That was my whole problem that I had the node number written out rather than the node number converted to hex. 139 was the node number which when I used 8B instead everything started working

It looks like you are trying to send the ASPP3 command. This command is only supported by our very recent generation of products (G-Link-200, V-Link-200, and the WSDA-200-USB BaseStation).

Since you are mentioning a Serial BaseStation, I'm thinking you don't have the WSDA-200-USB. Therefore, can you try the Ping ASPP1 command?

I am now able to get some response so that is better. When I send 01 I get back 01.

I tried doing the Ping ASPP1 command (AA05 0001 3902 0002 0142) but I got back 21?

So then I tried pinging the base station (V2) which I was hoping was simpler with AA0E 3012 3402 0001 1275 and still got back 21.

I assume 21 is some sort of error message? I have confirmed that this HW works in Sensor Connect.

Is the Node Address of your Wireless Node 313 (0x0139)? Assuming that it is, your checksum is incorrect, which is likely causing the problem. It should be 0x0043 instead of 0x0142.
0x05 + 0x00 + 0x01 + 0x39 + 0x02 + 0x00 + 0x02 = 0x0043

As far as the BaseStation command you are trying to use, it may be a similar case of that command not being supported by your hardware. Can you tell me what the firmware version of your BaseStation is (from SensorConnect)?

Also, could I ask what you are trying to achieve? I'm curious if you've looked in to MSCL, as getting that up and running would save you from having to worry about how the actual protocol works at a low level. Feel free to PM me at [email protected] if you prefer to chat about your project offline.

Oh, and 0x21 is indicating that the command failed.
