Hi,

   I just tried the NCP throughput tester on an MG13 and it works just fine for me. I suggest that you check your COM port settings.

To reiterate, I really don't think that this is the best way for you to implement what you asked for at the beginning of this thread. If you want to do a serial communication channel, we have the SPP over BLE article for that.

Hi,

   no, you do not have to call that API. If you don't have any specific timing/duty cycle requirements you can just let the stack use the defaults 10ms window/interval.

Peng,

   You can go into the project settings and remove the binapploader.o file as shown in the attached.

You can use the following API to change the behavior

Hi,

   The 2.7.6 version is preferred because of some fixes. When the install button is greyed out it usually means that you need to install the updates on the product updates tab first.

Steve

Hi,

   resetting the NCP should go very quickly, much less than 30 seconds. Typical reasons for the NCP to fail to start up are a missing bootloader or mistmatched USART settings. I suggest that you try connecting to the NCP with bgtool (compatible tools in the launcher) If you don't get an answer, try reflashing the bootloader.

Steve

Hi,

   Can you please get a packet trace and bookmark the place where the connection is first dropped so that we can have a look? This will help us understand if the stack has crashed (by determining if the device starts advertising again after the connection is dropped) or if there is simpler timing problem.

You can also try updating to the latest SDK, 2.13.6.

Hi,

    If you want a serial datalink, you would be better off using the SPP over BLE KBA here https://docs.silabs.com/bluetooth/latest/code-examples/applications/spp-serial-port-profile-over-ble. If you use the 2Mbps PHY, which the BG22 does support, you should be able to get the data throughput that you're looking for.

Hi,

   You can find this information in the module datasheet

https://www.silabs.com/documents/public/data-sheets/efr32bg13-datasheet.pdf

You'll see the maximum load current depends on the DCDC converter mode used.
