Is it possible to set ANT+ transmitter power levels with the Android-level SDK.
Also, is it possible to get the RSSI values from the ANT+ RSSI status register on the WiLink 6.0 chip that is currently used in Sony Ericsson Android phones?

Hello,

We are currently working on the documentation for that feature. This documentation will be released to the public when it is finished.

Best Regards,

Kassandra

Are there any developments related to this? It should not be difficult. The ANT_LibConfig allows for extended packet reception. The android receiver-buffer only gets more data.

For information on using the RSSI feature please refer to AN16_RSSI_Extended_Information in the Application notes section of the developers zone (http://www.thisisant.com/pages/developer-zone/ant-application-notes).

The Android ANT API does not currently have an ANTLibConfig function which is needed for RSSI, but the message can still be sent using the general ANTTxMessage function of AntInterface.

Controlling TxPower can be done per channel using the ANTSetChannelTxPower function.

Yep, it works well on Xperia S and Active:

public void ANT_LibConfig(byte libConfig) throws AntInterfaceException {

        byte[] enableExt = new byte[4];

        enableExt[0] = (byte) 2;

        enableExt[1] = (byte) 0x6e; // Lib Config

        enableExt[2] = (byte) 0; // filler

        enableExt[3] = (byte) libConfig; // 80 Channel ID;

                                            // 40 RSSI;

                                            // 20Timestamp

        antInterface.ANTTxMessage(enableExt); // enable extended format

    }

I managed it to work with RSSI and Channel ID. But with Timestamp (0x20) I always get the error INVALID_PARAMETER_PROVIDED. Does anyone have managed Timestamp to work with the sony ericsson active? My code:

byte[] txBuffer = {(byte) 0x02,(byte) 0x6E,(byte) 0x00,(byte) 0x20}

Thanks
Michael

What phone are you seeing the INVALID_PARAMETER_PROVIDED error on? and what version of firmware does it have? You can find the firmware version by sending a request for version message AntInterface.ANTRequestMessage(0, AntMesg.MESG_VERSION_ID);

I configured timestamps on a phone we have here and it worked correctly

Phone:
Sony Ericsson Xperia Active (ST17i)

Do you have the same or a newer version?

Thank you for your help

Unfortunately extended messaging with timestamps is only in version AOV1.15B00 or later. It was omitted in earlier versions because of code size constraints.

Can the firmware be updated? How can this be done?

Thanks

Updating the firmware requires rebuilding the phone's system image, which is not possible with a consumer build. Your carrier may provide a system update, but you cannot update the firmware yourself.

Hi,
I know this is a rather old topic but I couldn't find a better solution for my issue.
I want to get RSSI messages from an ANT+ heart rate device.

Is the way described here the only way to config RSSI messages for ANT+ devices?
If so, can we still use the ANT+ plugin to deal with the rest of the message while getting RSSI through the ANTInterface?

Thanks,
Iuri Andrade

Hi Luri,

The existing information in this thread is from before there was an ANT+ API (and the ANT+ Plugin Service) - so you should disregard it. RSSI updates are available during a multi device search (MultiDeviceSearch.RssiCallback), with the latest beta release candidate including RSSI while connected (AntPlusCommonPcc.IRssiReceiver : "Add an RSSI event to most devices" - I haven't tried this yet).

Much easier!
