BLE.connect causing "assertion failure" crash

This seems to be a "double post" of this

(I locked and hid the former thread for that reason)

Even if you don't get an answer to that question on your first post it's not appreciated to open an new thread for the same thing again.
You may ammend or bump your original post but don't double post - it just scatters the conversation, potentially ties down resources on multiple fronts for the same thing and won't add value to your request.

BTW, it's just 2 days since your original post and these were weekend and bank holidays.
