I use nrf51822qfaa,s110,keil,etc.
Hi, Guys,
I have a question about chip operation temperature. Will the chip auto reset when the temperature over 75 C? I checked the nRF51822 product specification v3.1...
I would like to learn more about when it is safe to invoke soft device methods and when it is not. For example, are the following 'allowed' to make soft device calls to update...
Update to below: I get data out of the VCP and into Termite for a sub-second when I first power the board (with handshaking enabled), then I get no subsequent data (even though...
Hi,
I have just received a bunch of N550 modules and now I want to try and see if it is possible to update the firmware of these devices without using a JTAG.
If I understand...
