Problem with Connection Parameter update in custom board

[balaji]

Hi, Our custom board stops working after updating the connection parameters. We have a nrf51822 chipset custom board with proximity application flashed on it. Device get disconnected after connection parameters updated (reset and advertise again). But the same application works fine in evaluation boards.

I measure 140 mA from my device after power reset (no advertisement, maybe off mode), flashing the application again or selecting the device from nrfgo studio wakes up the device (advertisement starts).

Here i attached the MCP log file, please refer it and suggest me to overcome this issue.

Regards, Balaji

140 mA?! Is that your expected current draw?

I am little confused Haskon, if there is a short, my device should not work always. But it is working fine until i do power reset, only power reset cause the problem. And enabling the connected j-link also recovers the device to advertise(how?). Anyways we will check for the short as you said. If u got any logic on this issue please inform us.
