We are using the nrf51822 chip, however after typing the command: nrfjprog --memrd 0x10001080 -f NRF51, the chip is no longer able to start. We have tried resetting the chip using nrfjprog --recover, nrfjprog -e, and nrfjprog eraseuicr but still the problem with the chip persists....I am still able to do normal read and writes in the memory, but without the chip starting -- I will not be able to detect BLE on the device.  Thank you in advance.  ...

Hi Everyone,I have successfully configured RTOS and BLE alog with onboard LEDs blinking into an RTOS code.Everyhting runs fine if i run only the 4 tasks of LED blinking but the code freezes after a while of working when i put in a task of ble in which i am sending a char over BLE to android app nrfConnect.Does anyone here have any idea ,what might be the reason to this problem?Thanks Rajat!...
