Get RSSI during connection

[rosek86]

Hi,

Is there any way to get RSSI during connection? I was trying something like this but this:

 (this.adapter as any)._adapter.gapGetRSSI(this.peripheral.connectionHandle, (a, b) => {
   this.logger.info(a, b);
 });

but this generates this error:

 undefined Error: Error occured when getting rssi. Errorcode: NRF_ERROR_INTERNAL (0x3)
 logMessage: Failed to receive response for command
 status: {"id":4,"name":"Unknown value","message":"Error sending packet to target. Code #3","time":"2017-04-14T09:50:47.269Z"}

It seems also that the error is second parameter in gapGetRSSI callback.

Kind Regards,
Krzysztof

Hi,
the way you are calling the function is correct and should work, but there seems to be a bug in the underlying function implementation somewhere. We'll have to look into it.

There is a bug in the connectivity firmware project for sdk 11.0. The SD_BLE_GAP_RSSI_GET function is missing from an array in middleware (components\serialization\connectivity\codecs\s130\middleware\conn_mw_items.c), so the connectivity fails during runtime when it receives a serialized function it doesn't have handler for. Adding a line for rssi_get in conn_mw_items.c seems to fix the problem.

Note: the function also seems to work out-of-the-box for SD API v3 (sdk 12).

Note2: Remember to call _adapter.gapStartRSSI first.

@bihanssen I am running into a similar error where I see NRF_ERROR_NOT_FOUND (0x5). Adding which line in conn_mw_items.c might fix it? Thanks!
