Dear All,

We are trying to send data to mobile but facing below problems:

1. I am using Gatt_Server_service_table for transmisting data to mobile app. but confued how to do.
2. We need send large mount of data please suggest proper eample which example need to use.

Thanks for your response....

We have fixed this problem by adding one line code after Serial2.end();

gpio_matrix_out(TX2_PIN, SIG_GPIO_OUT_IDX, false, false); // Workaround for use RX and TX pin as input after disabled Serial2

Now it working..

Hello to all, We are not able to use RX and TX pin as INPUT after when we used UART2 means Serial2 begin. In brief my program code flow as below: #define RX2_PIN 25 #define TX2_PIN 26 Serial2.begin(MODBUS_BAUDRATE, SERIAL_8N1, RX2_PIN, TX2_PIN); // read data from Serial2 // once completed Serial2.fl...

Hello to all, #define RX2_PIN 25 #define TX2_PIN 26 I have declair Serial2.begin(9600, SERIAL_8N1, RX2_PIN, TX2_PIN); and need to disable UART 2. For this used Serial2.end(); After that but TX2_PIN not working as input. Is any configuration need to be done when disabled UART2 for working RX and TX p...

I want to do same If power failing detect BOD and store one value in flash. How I can do it this possinle using NVS.

I am tring but still not able to store value when BOD happen.

Can you please suggest BOD example and how to store some value in nvs.

Hello to all, I am trying to update ESP32 OTA using SIM800C module. I am using below API's: [Update.begin(total_file_size); if (Update.write((uint8_t*)json_buff, data_size) != data_size) { Update.printError(Serial); }] If writing completed then call: [Codebox=c file=Untitled.c][if (total_file_size =...

Thanks for your suggestions.
Now we are able to read version data from ADE chip by changing VSPI to HSPI then communication done.
But problem for transmitting data to ADE chip address and value.
How I know whether data successfully transmitted as per send address. IS there is any way to check that?

Can you please give me ans of few questions: I am trying to read version of ADE9000 chip for SPI communication with below code uint32_t ade_get_version(spi_device_handle_t spi) { uint16_t Address = 0x000004FE; //Address of read ADE version 16 bit address uint16_t temp_address; uint32_t returnData; /...

I am getting strange for next What should I do now, We need to find solution as soon as possible. My other confusion is it neccessary to send dummy byte to read bytes from slave. I am send 16 bit address to read interface ADE chip version. Here is below code: [void ade_cmd(spi_device_handle_t spi, c...
