Data size limitation

[pavan]

Hello All,

I am working nrf51DK and i am using ble_app_uart application with s130 softdevice. Now my query is I am trying to send some data from my mobile application to ble chip(nrf51dk) but when i send more than 20bytes the dk get resets. so is there any limitation on data packet size , if yes how to increase the same?

please advice

thanks in advance pavan

There are certain limitations in the examples but BLE as such as well as Nordic BLE UART Service don't have any limitations which you couldn't overcome. If your chip resets itself then you probably encounter some hard fault or asserted error return from SD API. Please debug your FW, find the line in your code which invokes this assert and fix it.

Hello Sir,

Thanks for the information.

I have requirement of send 255bytes of over BLE and then in turn i need send that received 255 bytes of data via UART to ECU.

Now i am ok with sending split data i.e packet of 20 bytes of data sequentially. but now my query is my ECU will response only when it receives 255 bytes of data. so please advise on how and where to store the received split data of 255 bytes ans send full 255bytes of data via UART?

is there any code for such application?

thanks in advance
