nRF51822 reset during BLE connection/transfer

[Andreas]

Hello,

in our application I can see, that sometimes the nRF51822 completely resets, during a BLE transmission. I am using S120 as peripheral. The peripheral is connected to a peer (smartphone). Now the central (smartphone) tries to send some data. Sometimes, this operation works and sometimes, a reset on the peripheral side occures. At the moment I try to debug the connection with the sniffer. Maybe there is something wrong with the UUIDs or the data length. But is there an opportunity to debug such an error on nRF51 side? I think I have to implement some kind of error handling on the peripheral side, so that the nRF51 doesn`t run into reset. Which options do I have?

Regards, BTprogrammer

Which version of the S120 are you using? Please upload a sniffer trace showing the issue when you see it. Note that the error handler would normally call NVIC_SystemReset(); Add a define for DEBUG and you should be able to get the filename, error code, and line number of the error.
