Hi All: i made a nrf52832 board, but i test it, the frequency offset is 150K, it's too big. what can i do to change it by software ?

What frequency offset, how did you measure it, what do you mean by 15K? You need to ask a better question.
sorry, i am so simple describe this problem. i describe this again. now , we are making own board. and we need have a best antenna performance. we use DTM demo in 14.1SDK to test this(Mode Transmit, Channel Single 0, payload model: Constant carrier, and Start test.), in my tester show own board transfer 2402M Hz offset +110K compare with normal 2402Mhz, so i know this is need modify hardware. but i want to know whether other tools can do it by software.
Hi,
With a constant, unmodulated carrier, an offset at 15 kHz is perfectly normal. I'm measuring an offset at 25kHz here. With a modulated carrier (when you are sending data) at 2402M Hz, you should see ±250 kHz offset.
my write it wrong. In fact the offset is 150K.
i have another problem , uart input data, and BLE(peripherl) output to remote. my software max speed only 3K+, but my other bluetooth IC can do 7K/s, i don't why. connection interval and mtu all update.
Are there and other parameters affect it ?
software device is s132_nrf52_5.0.0 and IC is nrf52832. uart baud is 115200. MTU is 182. connection interval is 15ms.
my write it wrong. in fact offet is 150Khz.
