Hello Everyone,
I am using nrf51822 (BLE) and TD1208 along with the external GPS receiver , the reason for using the NRF51822 is to flash the firmware on the TD1208 without using the USB cable , as i found the information on the NRF51 it has internal bootloader functionality so i can use nrf51 only for flashing the FIRMWARE TD1208 could anyone verify my logic whehter it is possible to flash the firmware via NRF51 if it is possible which possible connections do i need to make communication between the TD1208 and NRF51 can i use SPI interface or please propose me some suggestions so that i could try to find a solutions for updating my firmware on the TD1208 without using any sort cableUSB
