I'm debugging an ESP32-S3 module at the moment with a very high deep sleep current. That device is not running much more than a Bluedroid BLE GATT server and is built onto a custom PCB. I've isolated all other power consumers on the board, so the ESP is the only thing running. I've attempted to isol...

Hi there, I'm having a difficult time connecting an Macronix mx25R6435FM2IH0 to an ESP32s' QSPI bus and was looking for some advice. I've removed the chip from my board and have connected it directly to an ESP-WROOM development module as follows: Q = GPIO12 D = GPIO13 CLK = GPIO14 CS = GPIO15 WP = G...

Looking for some architectural advice here if anything. I'm writing an application that uses the UART libraries to communicate with another 3rd party piece of hardware over RS485. There is one particular binary API that I'm calling which returns in the hundreds of KB of data over the 9600 baud seria...

Hi there, I'm building an offline IoT device that has the ability to run on it's own, but also to connect a number of units together to act as a single unit. I'm thinking the best way to achieve this is that the device will act as either a Master or a Slave. I'd like to build a sort of zero-touch-pr...
