BG96 keeps giving me +CME ERROR : 0 at first try of QFTPPUT

IoT Modules LPWA Module

Hi all,
I am getting this output systematically. Especially the +CME ERROR : 0 … This grind my gears. I retry directly and then it usually gives me +CME ERROR : 609… Do you have any idea why this does not work ?

Hi Loic_Gillioz ,

  1. Please use a specific file name , instead of < File >
  2. CME err 0 is a genernal err report , err 609 means system time out .
  3. pls refresh fw , and try again , Maybe the Position 0 has been occupied .
