I use HM-10 board (CC2541 inside) with HM-Soft V540 firmware to make IBeacon devices. But I have a big problem: I configure the HM10 as a beacon, with auto-sleep etc etc, after reset, the HM-10 is sleeping and advertising (2µA when sleep) but after a random time (a few seconds or a few minutes), the HM10 wake up and consume between 15 and 20mA... all the time !! Until I send "AT+RESET" for re-apply the sleeping. (and again, wake up after some seconds...)

This is the commands that I used to set the HM10:

AT+RENEW
AT+RESET
AT
AT+MARJ0x1234
AT+MINO0xFA01
AT+ADVI9
AT+NAMEFAB1
AT+ADTY3
AT+IBEA1
AT+DELO2
AT+PWRM0
AT+RESET

Do you know where is this issue ??

Thanks a lot for your help.

You should change your PWRM0 to PWRM1 worked for me

Guess the problem might be solved for you but as I just run into the same "issue" with the HM-10 (firmware version v549) I wanted to share my solution/finding:

In my case I have figured out that some logger within my code is sending a string of characters via serial extending 80 char. This is actually also the rule that forces the HM-10 to wake up from sleep. So you might use AT+PWRM0 (which enables autosleep) but also make sure that when sending data over serial the string length might not wake up the HM-10 accidentally. Hope this helps a bit.
