NRF52810 Notify Limited By CONFIG_BT_NIMBLE_MSYS1_BLOCK_COUNT #53

Closed jackb60 closed 2 months ago

jackb60 commented 2 months ago

I am using a NRF52810 with <NimBLEDevice.h> and when an attempt is made to notify with a characteristic length of greater than 339 bytes, the central does not recieve the data and onStatus indicates a return code of 6 (operation failed due to resource exhaustion). That may also be the case with other operations but I only tested notify.

I was able to get it working by changing line 13 in nrf52810_nimconfig.h from

#define CONFIG_BT_NIMBLE_MSYS1_BLOCK_COUNT (8) to #define CONFIG_BT_NIMBLE_MSYS1_BLOCK_COUNT (12)

That's exactly the correct solution 👍. Please see my comment here for a per sketch configuration solution to this.

Per my comment there you would add this: -DCONFIG_BT_NIMBLE_MSYS1_BLOCK_COUNT=12 to the build_opt.h file.
