I have an E22-900M22S ebyte module connected to an ESP32 board. Upon issuing the sleep command from a standby state, the module consumption stays the same. It is around 545µA, which is consistent for the standby mode, but do not drop any further down after the sleep command. I have tried multiple ebyte module and also 2 different ESP32 board, same same.
I am using the RadioLib and the modules are capable of transmitting and receiving.
The SPI bus stays active during the life cycle. Any idea what could be the cause?
Ensure both RXEN and TXEN are LOW, you can also try making sure the chip is deselected via NSS. Do all other chip functions work correctly?
