Hi,
i m doing a project which consists of esp32 & tft display. i want to transmit the byte
(for ex: 0x00,0x01 - nearly it goes to 1000 datas) datas to esp32 via bluetooth.Bluetooth communication is working fine. i m reading the incoming data in String variable, but i want to convert it to unsigned char array [unsigned char bitmapArray[] PROGMEM = {}; ] i m not able to do it. please help me.
Thanks in advance.
