hal_pwrmgr_RAM_retention(RET_SRAM0|RET_SRAM1|RET_SRAM2); hal_pwrmgr_RAM_retention(RET_SRAM0); During sleep, the LDO switches to 0.6 V and the leakage currents to different SRAM blocks are different.

I tested on the [PB-02-Kit](https://docs.ai-thinker.com/en/blue_tooth_pb) by cutting the power wire of the module on the PCB. But on other outputs of the module, leaks are possible... A lot of consumption...

It is possible to read the firmware using a programmer. OTA function does not support reading program dump. For example, CGD1 thermometers have different chipsets: TLSR825x or [nRF52xxx](https://pvvx.github.io/CGG1_old/) For TLSR825x:...

Version 4.8 is still in beta. There are many changes in this version and not everything is tested yet.

I don't have CGG1-T and I don't know what chipset is used.

nRF52x chips have OTA firmware locked with a key. Use JTAG.
