WL18xx adaptivity testing during certification

This has been resolved in SP 3.3 - please use this fw version (https://github.com/TI-ECS/bt-firmware/blob/master/TIInit_11.8.32.bts)

Thanks Gigi,

1) This is the BT driver only, do you mean adaptivity is not related to Wifi as well!?

2) How do we get to know about these release-notes & updates?

Oh, one more thing:

We're on AM3352 and linux 3.14, should we use the master/* or the am335x/* one?
I can see they differ a little bit.

Hi David,

1) By Adaptivity, I assumed "Adaptivity (Adaptive Frequency Hopping)" as per ETSI EN 300 328 V1.8.1 document. Is this not correct?
2) At present, you can check github.com/TI-ECS/btfirmware link for updates to BT firmware. Unfortunately, the release notes are not available externally.
3) You can use tree/master/am335x/TIInit_11.8.32.bts

Gigi Joseph.

Ok, we will monitor this page, but please consider an official newsletter / PCN via ti.com so we can know when the Wifi & BT firmwares are updated for Wilink8.

Please explain,

• what exactly is the difference of the am335x vs the bts in the top-folder?
• also curious why there are two with the same filename?

Hi David,

Q: According to EN 300 328 V1.8.1_4.3.1.6 & 4.3.2.5, adaptivity test is base on output power level, no matter it's Hopping systems or not. So it applies to BT & Wifi (2.4G/5G)
A: For WiFi, we will support ETSI 1.8.1 only with R8.4 release

Q: Ok, we will monitor this page, but please consider an official newsletter / PCN via ti.com so we can know when the Wifi & BT firmwares are updated for Wilink8.
A: Definitely, we will make an announcement on the e2e

Q: Please explain,

• what exactly is the difference of the am335x vs the bts in the top-folder?

A:

• One sets the baud rate command, the other doesn't
• The name is specific for the chipset - the ST driver will query the local revision of the chip, and then searches for the corresponding bts file in the filesystem. So the name has to be the same

Thanks Gigi,

We're very eager to get our hands on the R8.4 release (dm' me if it's possible to get a pre-release)

About the .bts, sorry for many questions, but the 

- which one sets the baud-rate, the root-dir or the am335x one?

- why is this different?

- the root-dir (if it's not for am335x) what is it aimed for?

Hi David,

Its more a legacy folder structure. The ones using TI ST driver does not need to set the baud rate command as it is done inside the driver. Other projects that does not use ST driver (non Linux) needs to set the baud rate.
Anyway, we are planning to do a clean up of this folder structure... Hopefully the confusions will go after that.

R8.4 pre release won't be available. The release itself should be available in 4-6 weeks' time.
