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. I'm sure my issues revolve around properly setting up paths, includes, etc - basic environment setup, and eventually I could figure it out, I j...

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.

Build errors at Makefile.projbuild

Switched over to Windows 10 from linux/eclipse because I'm fed up with eclipse issues. But I'm having a hard time getting projects to compile. Followed windows setup in documentation. Using VS Code. 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

Has anyone had success using android client to get requestMTU to work? Works fine in nRF but I am getting a status of false on my android callback to the command. 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...

Re: BLE event indicating client has changed characteristic value

yep, that is consistent with where I'm at. So, my server (the esp32) is the primary changer of data which the client (in this case, the phone) gets notified of changes. That is all working well. I do need to set up the ability for the phone to occasionally send data to my device and herein lies my q...

Re: BLE event indicating client has changed characteristic value

I've configured the device as a BLE server - my rationale is that the majority of communications will be outbound data from the device.

Inbound data is primarily for device configuration.
