Interfacing an nRF51 with an ESP8266 using AT commands over UART

[Sensors]

Right now I'm trying to interface an nRF51822 set up as a central to an ESP8266 module. The module is controlled by AT commands, and usually issues a response.

I'm struggling to figure out how to determine if a command has been a success. The arduino way of doing things is usually much higher level and allows there to just be a short delay implemented followed buy a string comparison.

How would I achieve a similar thing with the UART interrupts and a soft device running too?

I need to send a series of AT commands, and the response varies with each command.

Nothing specific to ESP8266 - it's the same for any device using AT Commands:

You need to study the AT Commands Manual for the device: that will tell you what response(s) can be returned by each command - and which of those indicate "success" or "failure".

The key thing is not to rely upon delays - always pay attention to the responses.

That's helpful to know, thanks.

You don't happen to have any examples of how to deal with AT responses, do you? I'm still unable to figure this out unfortunately. I just can't see how to utilise the UART Rx callback to record the stream of character responses, and then check this against what I might expect the response to be...
