Hi,

I trying to add esp_rmaker_obj() parameter to a Switch device.
After firmware program when I try to set JSON object value as mentioned below, I getting error in JSON parsing at esp_rmaker_handle_set_params() in esp_rmaker_param.c file and I am not receiving write_cb().

JSON Object value which I am trying to set is

Code: [Select all] [Expand/Collapse]

{\"name1\":[{\"name2_1\":\"value2_1_str\",\"name2_2\":val2_2_int,\"name2_3\":val2_3_int},{\"name3_1\":\"value3_1_str\",\"name3_2\":val3_2_int,\"name3_3\":val3_3_int}]}

Also after updating this value from App, I receive JSON data as below

Code: [Select all] [Expand/Collapse]

{"Switch 1":{"mapping":"{\"name1\":[{\"name2_1\":\"value2_1_str\",\"name2_2\":val2_2_int,\"name2_3\":val2_3_int},{\"name3_1\":\"value3_1_str\",\"name3_2\":val3_2_int,\"name3_3\":val3_3_int}]}"}}

Also please note that in parsing jsmntype is assigned as JSMN_STRING, I think it should be JSMN_OBJECT for correct execution.
Please let me know whether I am making any mistake here. If so please guide me on the same.

Thanks in advance.

Regards,

Dinesh

Hi Dinesh,

As per my understanding, you have a device named "Switch 1", with a parameter named "mapping" whose type is JSON Object, right? Note that the RainMaker phone apps do not support JSON objects. The textbox is shown just because the phone app does not know what UI to display. Any update from phone app gets pushed as a string rather than a JSON object, thereby causing parsing errors. A better option would be to use RainMaker CLI for your testing. Going ahead, we will add checks on phone app to handle arrays and objects properly.

Hi Piyush,

I have checked JSON value with RainMaker CLI and it serves my purpose.
Thanks for your quick and kind in-time help.
Further we will wait for app release for the same. I hope it will come soon.

Thanks once again.
