This may not be a direct answer, but I think the following link may help you.

Node using XIAO_nRF52840 and Grove-LoRa-E5 running on AT commands, sleep current 6.4uA

Using a XIAO_nRF52840 as the host controller and a Grove LoRRa-E5 as the LoRa module, I investigated how low the sleep current could be when a node was configured using AT commands only. I hope this will be helpful to those interested. The configuration is shown in the figure below, with 3.6V supplied from a PPK2 to the battery pads on the back of the XIAO, and 3.3V supplied from the 3V3 pin of the XIAO to the VCC pin of the LoRa-E5. The LDO of the LoRa-E5 has been removed to supply the 3.3V. …

Programming LoRa-E5 with Arduino, Grove-LoRa-E5 sleep current 0.7uA

In the link below I have investigated how low the sleep current can be when configured using the XIAO_nRF52840 as the host controller and using only AT commands and posted that it is 6.4uA. ‘https://forum.seeedstudio.com/t/node-using-xiao-nrf52840-and-grove-lora-e5-running-on-at-commands-sleep-current-6-4ua /273830’ The Wiki has an example of LowPower using the STM32CubeIDE without AT commands, but the STM32CubeIDE is too complicated for me. So I investigated how to program the LoRA-E5 using t…
