Hi Chen, As I know, BLE RSSI can’t be measured in standard DTM mode. Is it possible to add new feature in DTM to support BLE RSSI measurement? [vich] Yes, this is possible, but the command will have t

Hi Tommy, I don’t remember if DTM mode has any RSSI command in the Specification. Could you please elaborate on your requirements? Regards, Vinayak

Hi Jon, Could you please share a simple application or an upstream Zephyr sample that can reproduce this memory leak? From the look of it, the controller's rx buffers have been leaked. Is there any ch

Hi Martin, Adding Johan. The controller does not support multiple scan state instances. This is something in the works. Mesh stack implementation utilizes standard BT 4.0+ controller features, and no

Hi Vikrant, It appears a recent merged PR has introduced regression. https://github.com/zephyrproject-rtos/zephyr/pull/10289 I am analysing the issue, meanwhile you can revert the said commit so as to

Are you still receiving MPU Fault? I have solved someone's similar problem., and had a question if you are using GATT API and by any chance the control flows through bt_att_req_send function? -Vinayak

Hi, Only 5 of the pre-programmed PPI can be reused in Zephyr's BLE implementation. But the task to refactor the controller is not simple (i.e. not doable in a day or two). In upstream Zephyr, PPI's 16

Hi, The pre-programmed PPI are very specific to Nordic's in-house stack implementation needs. Some of them coincidentally can be re-used in Zephyr implementation. I will try to send a PR by EOD, if it

Hi Christoph, Yes, you can start with a copy of the board closest to your custom board and update the files to match close to your product, preferably the board name is easily relatable to the board g
