Master control panel error: no response from master emulator PCA10028

[sue]

I am using PCA10028. I am not able to verify the output for given examples of SDK 12.2.0 that require master emulator or UART. I have the pin 0.30 connected to ground as well. I can see the device on nRfgo studio and erase and program it. I am currently using the MCP 3.10.0 and have even upgraded the drivers. I tried downloading the earlier and next versions as per the instructions on the developer zone. Could someone please help me with more possible solutions for the same. I am a newbie in this field any help would be appreciated. Thank You

Did you try flashing the connectivity firmware by clicking File->Flash programming" in MCP? I have seen some issues with the programming inside MCP, but the issue have been solved by opening nRFgo Studio, clicking "Erase all" button on the kit, and programming the connectivity FW manually. The firmware is stored in C:\Program Files (x86)\Nordic Semiconductor\Master Control Panel\3.10.0.14\firmware\pca10000\MEFW_nrf51822_0.11.0_firmware_1M.hex.

Hi Jorgen I tried flash programming and also tried programming firmware using nRFgo studio. I still get the same status: No response from master emulator

Have you tried using nRF Connect for Desktop? It can do most of the things MCP can do, and can be used for testing of many examples. Could you explain the issue with UART in more detail?

I have tried using nRF connect. It displays (NRF_ERROR_INTERNAL) error. I am trying to observe the simple output for the given ble_hrs exapmle. I am not able to scan any device or detect any device that says NORDIC or for that matter ANY device. AS for UART, after compliling the assignment i am unable to observe anything on the terminal.

Could you try erasing the device using nRFgo studio or nrfjprog before starting nRF Connect? nRF Connect should then ask you to flash the required firmware. Are you sure the examples you tested are printing anything on UART? Try the UART peripheral example or the BLE UART example, these should print to UART. Are both devices (the board running the application and the board used with nRF connect) PCA10028?
