CC2650: CC2650 is not reading full Uart input

Hi,

I'm developing CC2650 to read a serial electricity meter. From electricity meter CC2650 is receiving 9 bytes as per reply. From electricity meter cc2650 is receiving one reply(9 bytes) per minute. In CC2650 I edited udp-client.c to receive serial inputs. The results are as follows,

Here one reply means 1,4,4,66,124  / 1,4,4,66,124  etc.

But there are not 9 bytes.What happened to other bytes?

I read serial electricity meter using an arduino uart. The results are as follows,

Here you can see arduiono reads whole reply. Ex Here 1 4 4 42 47 CC CB 7C   is one reply from electricity meter.

My problem is why cc2650 is not reading whole reply. Contiki-OS-Udp-client.c is the edited code i'm using,uart communication. Electricity meter's one reply consists with 9 bytes which are hex values.
