Hi, For Ios, I suggest you see the Nordic github repo: https://github.com/NordicSemiconductor/IOS-nRF-Toolbox For Esp-Idf BLE samples: - Kolban libraries on https://github.com/nkolban/esp32-snippets - pcbreflux ble_uart_server on https://github.com/pcbreflux/espressif (I use this with Nordic ios/and...

Hi, I made one header file (log.h) to use in esp-idf projects to improve the logging. Are simple precompiler macros to ESP_LOGx and ESP_EARLY_LOGx, thats extends the powerfull esp-idf logging with: - Show the function name thats the log origins This is usefull to debug, without need put function nam...

Hi Fugazi, I will make it in future, a complete sample solution for Esp32 BLE, with Esp-Idf firmware, Android app in kotlin, iOS app in swift 4. I need prepare all, and translate all code and apps to english. But I dont have time now for this, but I post here when it is done. I see this is important...

Hi, chegewara Situation you are describing here is true because esp32 by default has set local mtu value 500 if i remember or something around it. Its developers implementing choice. Usually the ESP32 act as server and mobile App act as client. MTU -> Who's the boss? is the client! In this case the ...

Hi, What I learned about Ble MTU: - Who changes the MTU is the client, the server receives the event of this change - Usually ESP32 is the server and APP mobile is the client, in this case you only need to change your code for Android, since iOS already changes the MTU automatically to 185 (iOS10 an...

Hi peterlspot,

Very good question, I too have projects only BLE and I too want binary without Wifi Stuffs

And I planned do OTA by BLE, if without WiFi stuffs, this is will more faster.

Hi, ESP_Sprite Thanks for you response. I modified the program to do benchmark in core 1 too: /* * main.c * * Created on: 9 de jun de 2018 * Author: Joao Lopes */ #include <stdio.h> #include <stddef.h> #include "esp_types.h" #include "esp_system.h" #include "esp_log.h" #include "sdkconfig.h" #includ...

Hi, Fugazi Find it quite strange no one is using the Iphone and the esp32 for BLE and theres examples out there ??!?!! I not agree that, I use with success esp32 BLE with iPhone and iPad, iOS versions 10 and 11, much estable for my app :-) What is the interval of time you send messages to iOS? Have ...

Hi, I did a benchmark of DAC x Sigma-Delta: /* * main.c * * Created on: 9 de jun de 2018 * Author: Joao Lopes */ #include <stdio.h> #include <stddef.h> #include "esp_types.h" #include "esp_system.h" #include "esp_log.h" #include "sdkconfig.h" #include "esp_timer.h" #include <driver/dac.h> #include "...

Hi,

The Ble support large messages by changing the MTU, and iOS change it automatically to 185 (in iOS 11 and iOS 10).

You can try, instead to send one message each 50ms, send one message each second with last 20 values.
