Which Jlink is compatible for iB004-N-pin and jtag?

[Shabi Zahra]

I want to program Jtag inside Anti-lost Tag nrf51822 Module Bluetooth Low Energy Sticker.

Following are the specifications of Anti-lost Tag nrf51822 Module Bluetooth Low Energy Sticker. Chipset is of Nordic nrf51822 Battery: CR2450 PCB size: 34347.5mm Housing size: 404015mm

I will make and Android mobile app from scratch to track the objects which are out of range or in range but not in the sight. These tags will attach to the items so that we can find them with our app.

Please tell that is Jlink required or not for the jtag programming in our situation? If yes, then which jlink is compatible for the jtag used inside the above mentioned tag? thanks

I'm not familiar with the iB004-N pinout, so it might be easier for you to compare its pinout with the J-link. So to program the nRF51, you need only 4 pins, VDD, GND, SWDIO and SWDCLK. You can always solder together pins if needed and make an adapter. The pinout of the Segger j-link is the same as described here.
