Re: ESP_GATTS_READ_EVT infinite loop

Maybe as alternative I should use ESP_GATT_AUTO_RSP instead?

Can I just maually edit my_data buffer?

ESP_GATTS_READ_EVT infinite loop

I have created custom characteristic using gatts table demo. I'm trying to establish manual responding on ESP_GATTS_READ_EVT . Problem: I got infinite loop when trying read characteristic value. my characteristic configuration: static uint8_t my_char_uuid[16] = { /* LSB <----------------------------...

Re: How to make 128bit service using ble gatts table demo?

Ok, I got working as I want with next settings: [IDX_SVC] ={ {ESP_GATT_AUTO_RSP}, {ESP_UUID_LEN_16, // why 16bits lenght? (uint8_t *)&primary_service_uuid, ESP_GATT_PERM_READ, 500, sizeof(service_uuid), (uint8_t *)service_uuid} }, And here is what nrfConnect shows: esp32_gatts_table4.jpg.JPEG.jpg Ca...

Re: How to make 128bit service using ble gatts table demo?

This is what i think (not what i know for sure): [IDX_SVC] = { {ESP_GATT_AUTO_RSP}, {ESP_UUID_LEN_128, (uint8_t *)&primary_service_uuid, ESP_GATT_PERM_READ, 50, // max service length (try some bigger value, you only waste few bytes or ram) sizeof(service_uuid), (uint8_t *)service_uuid} // service_u...

Re: How to make 128bit service using ble gatts table demo?

Thanks for the reply. Next you have to know that some values in GATT attribute table cant be changed: https://github.com/espressif/esp-idf/blob/master/examples/bluetooth/gatt_server_service_table/main/gatts_table_creat_demo.c#L167-L169 I want to change not this, but this: https://github.com/espressi...

Auto flashing error (GPIO0 need to be manually set low)

Hello! I'm using ESP32 DOIT kit. I flashed it automatically with onboard CP2102 usb-uart converter. But once I got app crash (says CPU halted) I'm not available to flash it in auto mode. Now I have to hold GPIO_0 on ground untill flashing will be done, even with fixed code its not flashing automatic...

BT SPP acceptor error: "Cache disabled but cached memory region accessed" while pairing

Hello, I'm running modified SPP acceptor example and WiFi in AP mode simultaneosly. Aslo there are deployed UART (GPIO 5, 18) and some LEDs (GPIO 13, 15, 21, 16, 17). I cant robustly pair via Bluetooth and esp32 from android tablet (i.e. I'm able to connect after 2-3 retries). Here is log: Guru Medi...
