It is for M5StickC Plus. M5StickC is nearly the same:

    Power consumption in deepsleepposted in M5 Stick/StickCHi all, 
 I want to reduce the power consumption of my M5StickC in deepsleep-mode. When entering the deepsleep viaM5.Apx.DeepSleep(10000000);the power drops to about 2mA with LCD turn off usingM5.Axp.SetLDO2(false);and
 M5.Axp.SetLDO3(false);
 With a thermal camera I found out, that the chip next to the display-connection gets hot (see pic) so I think this chip uses at least a part of that 2mA.
 Does someone know how to put this chip (name: M5A1 1220) in DeepSleep or what the pinout is to connect its VDD to a GPIO?Any other suggestions to reduce the deepsleep current? Thanks

    RE: ESP-Now UIFlow to Arduinoposted in UIFlowHey since you pass a pointer to the println-function and the cpu does not know what type of data is located at that position this behaviours seems normal. 
 In the example in the link they create a structure for the transmitted data. In the callback they copy the recieved data in this structure and later you can print exactly what you want:
