connexion problem with Galaxy Tab A6 10' 2016

[energy]

Hi,

I use sdk 12.2 for my production software with UART protocol, my product is distributed to customers since 6 months with many type of phone or tablets using it without any problem

I now got some 3 clients with galaxy tab A6 2016 10' model SM-T580 and SM-T585. They are all with Nougat version (it is not related to Nougat itself because apps and firmware works fin with S7, LG phone ... that have also Nougat).

I bought one and checked, it looks like the application crash and reset (not from APP_ERROR_CHECK, real crash "jump" to an invalid address code, no call stack.....)

I tried with original uart exemple APP of sdk 12.2 and 12.3 on PCA0040 board and using DFU toolbox and get exaclty the same problem. Crash and reboot of the nrf52 application

Here is the log of dfu toolbox http://hpics.li/86c0732

Could you try to reproduce, any idea ?

Many thanks

It looks that A6 is not compliant to bluetooth spec

devzone.nordicsemi.com/questi...

But Sdk 12.2.0 and 12.3.0 are compatible with only S132 v3.0.0 infocenter.nordicsemi.com/topi...

Which SDK for 52832 is compatible with S132 v3.1.0 ? Thanks
