Firmware Upgrade of JN5169 at Gateway End

       Hello, we intend to use JN5169 to develop a ZIGBEE gateway, but our embedded LINUX system hardware has no USB port, only UART port, so we can not upgrade JN5169 firmware completely using the method introduced by JN-AN-1222-IoT-Gateway-Host-with-NFC+v2007.

       We don't want to convert through FT232RL chip. GPIO port is used to connect directly with RESET port and SPIMSO port of JN5169, and TXD and RXD ports of UART are also connected directly. Is it possible to upgrade JN5169 firmware by using this hardware connection method? In addition, there are no relevant reference design materials.

Hi,

Is it possible to upgrade JN5169 firmware by using this hardware connection method?

Yes, The TX and RX pins should be connected, GND and the VCC. The MISO pin should be floating for programming mode. 

Please look at the JN-AN-1110. The zip file includes the JennicModuleProgrammer, so you must use as a reference to send the command for programming the JN devices.

 

Regards,

Mario
