Bluetooth crashing, pycom continuously resetting

[Dam]

Hello

I am running my first test on the LoPy module, and I want to test Bluetooth. I first updated the firmware to the latest version. I am trying to run an example from the doc as is.

The device keeps crashing and rebooting, as I can see in the logs. It seems that the problem is on the following line:

bt = Bluetooth()

In the logs, the only useful message I can see is:

/Users/danicampora/Code/Espressif/IDF/esp-idf-20171106/components/freertos/./ti!
abort() was called at PC 0x4008b84c on core 0

Am I doing something wrong ?
Thanks

Tried the 1.9.2.b2 and it worked.

Thanks for your help

Do you know when this bug has been introduced ? Which version should I choose ?

Thanks for your quick response Seb!

Could I revert to a previous firmware version to get this working ?
