Hi, I not tested use of gl_profile.gatts_if, maybe works I use an global variable for it: static esp_gatt_if_t mGatts_if = ESP_GATT_IF_NONE; And change the event: case ESP_GATTS_CONNECT_EVT: DEBUG("SERVICE_START_EVT, conn_id %d, remote %02x:%02x:%02x:%02x:%02x:%02x:, is_conn %d", param->connect.conn...

Hi, I suggest the nRF Toolbox App of Nordic to test Ble comunications, especifically UART, its is very good, and have code in github and an Ble Library to Android and iOS *** ble_uart_server (by pcbreflux) *** Send (by esp_ble_gatts_send_indicate) esp_ble_gatts_send_indicate(mGatts_if, 0, gl_char[1]...

Hi, In my project, I use pcbreflux ble_uart_server and based on Nordic examples, to make the Esp32 firmware and Android and iOS app. In my case, testing with iPhone 5, it had a higher performance and stability than Android 7.1. To help you, please give us more details: - Is your Esp-IDF code based o...

*** Update I found out here in the forum and on the internet, that is possible change the MTU of the BLE, besides the 20 bytes. Searching the internet, I also saw that iOS already does this, so we can send several messages without delay (necessary for Android) I worked to change the MTU to Android a...

Hi Deouss , I do this, thanks a lot

I see that top Arduino libraries for Leds, as FastLed, using RMT in Esp32, why not Sigma or Led Channel ?

Floats use the FPU while doubles are calculated in software. For reasons, using the FPU inside an interrupt handler is currently not supported. The sin () and cos () functions of math.h, is for double (as ESP_igrr said -> its is calculated by software and not FPU) Has anyone ever used fastmath.h? T...

Hi, Deouss, tanks for response

It has 8 channels exactly as you need and allows smaller frequencies too
I think that would be perfect solution here

How use Remote Control feature (RMT) to control brightness of leds ?

Hi, tcpipchip,

This is interessing:

You can inform the vendor of this module ?

Hans Dorn, Very good hacking, this save my day, I trying avoid to use FreeRTOS notify in my timer of 1ms to not overload the system.
Your code works very well

Thaks a lot

Hi, Anh-Minh I post now same examples of this (see below). I translate my code to english for this examples. *** This only for show how it works *** I not tested the codes it after translate, I will do it when I made the entire example for put in github *** After I post code for Ios in Swift 4, for ...
