Hi; I'm test this with one more android device and one more ESP8266 module. I use ESP8266, HL-340 converter and OTG cable. If I'm send AT+CIPMODE? command to ESP8266 I can't get answer. it seems like a UsbSerial BUG

If I'm send any other command to ESP8266 after send AT+CIPMODE? command (Ex: AT+CWMODE?) I get two answer with include AT+CIPMODE? answer.

I'm test it with example sync (https://github.com/felHR85/UsbSerial/tree/master/examplesync) result is same...

Hi @makarna35 Could you test with DroidTerm app (Google Play)? It uses UsbSerial library. Thanks

I am working with ESP8266 for fimrware Update. I converted https://github.com/espressif/esptool/blob/master/esptool.py to Android(java) For serial communication, I am using https://github.com/felHR85/UsbSerial.

I am using https://github.com/felHR85/UsbSerial/tree/master/examplesync. With FTDI, there is no problem. But, with CP2102, there is problem. The esp8266 cannot be firmware bootloader mode(https://github.com/espressif/esptool/wiki/ESP8266-Boot-Mode-Selection#select-bootloader-mode).
