Flash mac address 88w8987

Hello,

I want to flash new mac address in 88w8987. Using labtool I use the sequence:

2 => Use Bluetooth

Successful connect to hci1

45 => Read MAC from OTP

Get 41.41.41.41.41.41

46 aa.bb.cc.dd.ee.ff => Write MAC to OTP

Operation successfull

But after that the chip doesn't answer anymore to any labtool or hci command.

Spoofing the uart communication I get that:

< HCI Command: Read BD ADDR (0x04|0x0009) plen 0                                 #1 [hci0] 15.071800
> HCI Event: Command Complete (0x0e) plen 10                                     #2 [hci0] 15.074145
      Read BD ADDR (0x04|0x0009) ncmd 1
        Status: Success (0x00)
        Address: 41:41:41:41:41:41 (OUI 41-41-41)
< HCI Command: Vendor (0x3f|0x0061) plen 32                                      #3 [hci0] 21.770553
        00 00 01 04 37 0e 1c 00 ff ff ff ff 00 00 04 02  ....7...........
        00 00 00 00 c0 c6 2d 00 ff ee dd cc bb aa f0 00  ......-.........
> HCI Event: Command Complete (0x0e) plen 4                                      #4 [hci0] 22.240375
      Vendor (0x3f|0x0061) ncmd 1
        Status: Success (0x00)

< HCI Command: Read BD ADDR (0x04|0x0009) plen 0                                 #5 [hci0] 26.152425

Bluetooth: hci0: command 0x1009 tx timeout

I'm using labtool 1.0.0.146

Can someone can explain why labtool fail ? Or give me an other way to sent mac address to the chip.

Thanks

Best,

HI, I got the information from the apps team
The labtool version 1.0.0.146 seems to be an old version.
We are working on sharing the latest MFG Tool that should support this feature.

I just try the release 1.0.0.164 and it doesn't work. I link some new logs.

Do you know when an other release should be done ?
