We are using SPWF04 recently and found this module when running at standby mode would draw around >1mA current rather than uA level mentioned in the datasheet (it actually comes to uA for a couple of seconds and turns to 1.7mA after). May I know if SPWF04 could be a compatible replacement for SPWF01, any notice/tips for Hardware redesign, IO config or AT comment settings? Thanks.
Hi Elio,
This is really helpful. I will try and get back. May I know if there is an estimated timing for the next FW and UM? Thank you so much for your kind help. Have a good one.
Hi Elio,
We have done a further test with shorter time-out period (240 seconds or even 100) and the module behaves the same as the current draw still remains around 1.5 mA in standby mode... Could you please provide further tips. Thank you so much.
Hi,
all GPIOs are put in high impendence when the module is rebooted in standby mode (AT+S.PMS=3) and you should expect a current consumption around 43uA regardless what is connected to the GPIOs. When the standby time expires or GPIO[6] is moved then the SPWF04 is woken up and the current consumption will increase to the level of your specific configuration.
I kindly ask you:
- to dump and send me your configuration (AT+S.GCFG) and status (AT+S.STS) just before issuing the PMS=3 command;
- to verify the current consumption only comes from pin24 (Vcc) of SPWF04.
Hi Elio,
Yes. We leave all unused GPIOs open/floating and even tried to add RC at GPIO[6]. But the standby current is still holding at uA only around 4s and raise up to 1.7 mA. Please see the status query as you required below. Your comment and advice are much appreciated. Thanks a lot.

Hi Elio,
We are still keen to know your kind comment and advice regarding to this issue. The feedback is important to the decision making on whether to keep ST 04 module in our future products. Thank you so much for your great support.
Hello,
we are trying to figure out why your sample is consuming such amount of current.
I'll update you ASAP.
Elio
Dear,
could you please try setting standby_time=240? You should see the current consumption in the uA level for about 4 minutes.
Please do not use values greater than 255 as we found a mismatch with what stated in the user manual. The behavior will be aligned to user manual in the next FW release.
Regards
Elio
