BLE power consumption
Setting up a network with an ESP32 master and peripheral devices communicating to the master through ble. The peripherals need to be lower power but advertising so that they are available when polled by the master. Is there any information on current power requirements with ble only and frequent adv...

mbedtls doesn't release all resources
I'm working on https mbedtls and can't seem to recover all resources after finishing a function. I log starting freeheap before calling the routine then log at various points trying to understand where memory is being consumed. The https routine is a task. Max heap consumption is about 30k in the ta...

Re: Build errors at Makefile.projbuild
was trying to get away from eclipse. after spending hours trying to get vs code setup (in both windows and linux), I gave up and went back to linux eclipse.

Re: Memory consumption of bluetooth is enormous
any thoughts on what 'lowest possible values' might mean or how one might go about determining them?

Re: Need help to connect external 16 MB SPI Flash Memory on ESP32-WROVER Kit
Was curious whether you determined how you are going to resolve.
We are finding that 4MB will not be enough and cannot go with MOQ 5000 in order to have Espressif increase memory size.

When I compile, libraries are built but then process stops with following error: /bin/sh: python: com...

Re: How to increase MTU size on GATT - Server

The process seems pretty straightforward gatt.requestMTU(100). Tried issuing the requestMTU at various points in the connection process b...

Error receiving blecharacteristic value > 20 bytes written by connected client
Using Eclipse and ESPIDF most recent code. ESP32 is set up as client and ble communications work fine in general. When the client (nRF Connect for testing) writes a text value to a characteristic, the callback onWrite event is triggered appropriately. If the value is > 20 bytes, all bytes are succes...

i2c_master_stop: rc=263 Timeout
I have 4 i2c sensors communicating successfully. However, occasionally I will receive this error. It appears that the longer the app runs between re-boots, the more frequently the error occurs. This occurs with multiple ESP32 Dev boards (C). ESPIDF and toolchain all updated (as of today) but this er...
