Oasis - DFU - v30 - multipoint

Do NOT upgrade unless you are told to by Avantree support to do so.

(1) Connetion is not stable/ cut off

After connected with two devices, the LED A and B are lit up on Oasis

If one device is cut off sometimes and only one LED B is lit up. then A might be occupied by other unknow device.

Solution- Clear pairing histroy for all devices and take all of them into a car and pair them in a shield environment, once paired, they shoud be work well.

(2) Compability issue

Bluetooth multi-point technology works best with products using the same brand of chipset utilizing the same audio codecs. Our Avantree Oasis uses a CSR (Cambridge Silicon Radio) chipset and high quality audio codecs (like AptX-LL) that give us very good audio quality.
If the Bluetooth devices you’re pairing with don’t use CSR and/or use a more lossy audio codec then audio issues may occur (e.g. one of the devices don’t work, the audio occasionally cuts out or there’s echo).

Solution-- We have a modified software version (version 30) which you use to flash onto the Oasis that activates a lower level audio codec. While this software version can increase compatibility across more devices the trade-off is that there may be a negative impact on audio quality.

Here are the steps for flashing.
