I have managed this route UART -> SPP! :P As Markus said, I'm keeping handle for connection and then transferring it to my functions. And as chegewara noted about unions, I have remake my function for transferring handle, len&buffers (I'm pretty sure there was some mistake). Thanks you both! :)

param is type of union esp_spp_cb_param_t: https://github.com/espressif/esp-idf/blob/ff726b4c79194e6815d2e8567ec17f106425dc44/components/bt/bluedroid/api/include/esp_spp_api.h#L168 For this particular event it will be this structure: https://github.com/espressif/esp-idf/blob/ff726b4c79194e6815d2e85...

Why? It should be int type, not int*: https://github.com/espressif/esp-idf/blob/ff726b4c79194e6815d2e8567ec17f106425dc44/components/bt/bluedroid/api/esp_spp_api.c#L153 Yes and it is uint32, but in debugger I'm looking at param which comes as address. In debug log (under CASE in cb section) this loo...

handle is uint32_t type: https://github.com/espressif/esp-idf/blob/ff726b4c79194e6815d2e8567ec17f106425dc44/components/bt/bluedroid/api/include/esp_spp_api.h#L95-L99 but what is interesting its the len value, i dont think it should be as high, it looks more like address or wrong value. Yes, this is...

Thanks for advice Markus! I will controll connection status. But still I'm not sure how param handle should to looks like? void SPP_to_UART_write(esp_spp_cb_param_t param) { esp_spp_write(param.write.handle, MyData.UART_len, MyData.UART_buffer); } void app_main() { ... // maybe like this? esp_spp_cb...

Hi, I need to exchange data from PC (by UART) to smartphone over SPP. Data from UARTmust be send to SPP and SSP data to UART. Rout SPP-> UART works fine (thanks to loboris for assist ;) ), but I have trouble with handling esp_spp_write function in route UART -> SPP. Here is prototype: /** * @brief T...

Hi, I need that ESP can send and receive data over SPP while connected to Android smartphone (let say, using any spp terminal I need to receive and send commands). In IDF examples there are 2 examples for acceptor and initiator. I have checked acceptor and it works fine. Only one thing - it working ...

For example, you can create fithub repository which will be in BASE folder, then in this folder you can have as many as you wish subfolders and each subfolder will be separate project, like in esp-idf/example folder. Then you will import every single project to eclipse and work with it. When you ar...

Hi! I'm not so familiar with github and eclipse IDE, so I would like to ask some help. Some of questions may be pretty obvious, but I have tried to solve them by myself and didn't succeed. 1) how can I create global folder for projects in Eclipse Project Explorer? For examle, I want to make next tre...

1. How to read flash chip through spi interface. 2. How prevent others to copy my flash in the way as in the question 1 mentioned. :lol: Gfast2 1.
